Convert analog signals into I2C

hi all,
 I am using NI-6351 DAQ unit.I want to capture  two analog signal and I2S data from the hardware.
 Is it possible to do this?

Depends upon what computer you have.  You'll need a player with an output line of some sort, then a converter to go from analog to digital (e.g. http://store.griffintechnology.com/catalogsearch/result/?q=imic). then recording software (free Audacity).  Time.
Those are the basics. For higher quality you might want a soundcard that has RCA input and various software packages for cleaning up the audio.
How may cassettes? it may be cheaper to just buy the CD.  There are also commercial services that will transfer cassettes.  If you're just talking one or two I would go that route because you can spend a lot of time doing this and that will increase sharply if you haven't done this kind of thing before.

  • Converting analog signals into digital signals

    I have been transferring analog video cassettes to iMovie for further editing by using a digital camcorder (Canon MV960) between the 8mm video camcorder (analog camcorder) and iMac. I have always done this without any cassette in the digital camcorder, i.e. I have been using the digital camcorder as an analog/digital converter only.
    I recently acquired iMovie HD 6 but this most recent version of iMovie refuses to import any signal from the analog camcorder via the digital camcorder. The window in iMovie is empty with an error message saying that "no tape". Well, it's true, there is no tape, there never was any tape when I used the previous version of iMovie!
    Does this mean that I have to convert the analog video tape into digital video tape and, once recorded in digital format, the digital tape can be imported in iMovie HD 6?
    All cable connections are OK:
    - the analog film could be seen in the screen of the digital camcorder:
    - digital video tape could be imported to iMovie HD 6.

    Hi 5480:
    try running a permissions repair (which should actually be done before and after upgrading software). You will find it in applications / utility / disk utility.
    Also, this is a copy of how Matti Haveri (iMovie Guru) sets up analoge to DV:
    My Analog to DV passthrough settings memo:
    1. Take the tape out of the camcorder
    2. Connect the analog device's audio and video to the camcorder's minijack, use the S-Video jack for video if the output device supports S-Video
    3. Put the camcorder into VTR-mode
    4. Select A/V->DV out: ON, in VTR mode's menu choices
    5. Disable the info display on the the camcorder by toggling its DISPLAY button
    6. Put iMovie (or other DV application) to the Camera Mode
    The analog image should now appear on the camcorder's screen as well as on the iMovie's screen.
    Note that if you have a tape in the camcorder, you have to put the camcorder's VTR into REC mode (you may pause the tape) but this is not advisable because it produces wear to the tape.
    * Note that the SCART which comes with the European nEUtered TRV320E camcorder is Out-only.

  • Directly convert the analog signals into digital without passing through FPGA

    To whom it may concern,
    I am using a SCB-68 board R-series and I have a couple of technical questions:
    In my system at the moment 8 analog channels are connected to the 8 input analog ports and then data are sent to a FPGA (PXI system 7852R). I am planning now to add other 4 channels to the system. Since over the total 12 channels I just need a very fast acquisition mode (using the FPGA) for 6 of them, while the other 6 can be sampled in a ms scale, I was wondering if you can suggest me something that I can use to directly convert the analog signals into digital and in this way used many unused digital signals provided with this model.
    Thanks in advance.

    yes it is correct, what do you need is:
    software + (pc) + PXI + cable + chassis + C-series module
    With embedded controllers, there’s no need for an external PC
    With PXI remote control kits, you can control PXI systems directly from desktops, laptops, or server computers.

  • How to convert analog scalar into digital value

    I have the DAQ connected to a system that sends a digital 0 or 1 through the analog BNC connector. If I use DAQ Express VI, I can convert the dynamic data type into a boolean (rather than scalar) array so it's easy to check if the value is 0 or 1. Because I'm running the VI in real-time, I can't use dynamic-to-boolean array conversion. The output I get is a 1-D waveform array which will give me scalar values. The task has a voltage range of -10 to 10 mV. How can I convert that into a 0 or a 1? Should I set the voltage range to 0-5V and simply have an if statement that checks if the value is, let's say, greater than 2.2V (which will mean it's a binary 1)? Is there a better method?
    Thanks. 

    Hi abdel2,
    It sounds like you are trying to measure digital data from your system. If that is the case, you should be able to connect to a digital input line if your DAQ card had them. Then you can set up a digital acquisition in LabVIEW that will interpret the signal as a boolean input.
    If you are not able to do this, you can approximate the digital behavior by reading analog data, and pragmatically determining a threshold (for example 2.2V), though this is a less efficient way to do it.

  • Converting square signal into sinusiod avoiding Fourier Transform

    I have a clean digitized square wave signal with a frequency around 50 kHz and I would like to convert it into a sinusoid with the same frequency and phase (don't care about amplitude). I would like to do so avoiding the stantard approach that would be  doing the Fourier tranform to measure the frequency and phase and then generating a new sinusoid. Are you aware of any other procedure?
    Thank you!

    What's up with the FFT-phobia? Is this some kind of homework with silly restrictions?
    (Even the zero phase filter mentioned by Darin might use FFT like functions internally. )
    Keeping up the facade, here's one way using "extract single tone". (Which also uses FFT internally).
    Of course you could get a good initial estimate on the frequency and phase by measuring the zero crossings, then fit to a sine function with adjustable amplitude, phase and frequency using levenberg-marquardt. Suddenly, FFT seems like a better idea .

  • Analog Signal to Digital a Primer

    Many users have analog material sitting around, and they would like to get it into digital form, so that it can be edited. As this material is below SD (Standard Definition) quality, I will address the methods for digitizing it, so that it can be best edited in a DV Project. The output can be a DVD-Video, or other format, depending on what one wishes.
    The process of getting this analog material into a digital form, is referred to as Capturing, and it is digitizing the analog material and writing it to a file, that can be edited.
    One will need some method of getting the analog signals into digital form, and for connecting the analog output from their analog playback device to the computer. Though the analog signal could come from all sorts of devices, I’ll use a VHS tape deck in this example.
    Since a VHS tape deck does not have an A-D (Analog to Digital) processor, and also does not have a a digital signal Out, one needs something in between it, and the computer. That “something” serves two needs: mechanical connection of cables and the ability to convert the analog to digital for use in an NLE (Non Linear Editor). That “something” can be a digital video camera with pass-through capabilities, a device, called a “bridge,” or a capture card inserted into a bus slot in the computer. All three have pluses and minuses.
    The first two methods rely on one having a FireWire connection on the computer and will use the Capture module in the NLE software.
    The digital video camera route is good, as one already owns it. Having one with pass-through capabilities is getting more difficult. The camera also has to have FireWire (FW, IEEE-1394a, or iLink) output, and the computer must have a matching connection.
    An A-D bridge will do the same thing: allow one to connect the analog cables to one end/side, process the analog signals to digital and then output via FW to the computer. There are various such bridges available and two of the most often recommended makes/models are: the ADS-Pryo, and theCanopus/Grass Valley ADVC-110. Products, like the Dazzle lineup, just do not seem to work, or work well. I would avoid such.
    A dedicated capture card performs the same task, with one exception. The card will mount into an empty PCI slot on the MoBo, and have inputs for the analog cables. The card will have chips on it, to digitize the analog signals and feed these to the computer via the PCI slot. These do not connect via FW, but have one drawback: they must, in virtually every instance, use additional software to do the actual Capture, as most NLE’s cannot directly see and work with them. Some of the included software Capture programs are better, than others. One common issue with many of these cards is a loss of sync, between the Audio and the Video. This is usually static OOS (Out Of Sync), in that it is usually off by a fixed number of frames, and does not drift over time. This can be fixed in the NLE, but is extra work. This ARTICLE will give you tips on correcting OOS.
    Now, we are ready to begin the Capture, as our equipment and cables are all ready to go. We have a big decision in front of us - what format/CODEC do we use to Capture our digital files? Since we are doing an SD Project with non-HD (High Def) material, there is one fine choice: DV-AVI Type II w/ 48KHz 16-bit PCM/WAV Audio, using the DV/DVC CODEC. These files will be approximately 13GB / hour of Duration. Storage will need to be considered. These files are also I-frame, meaning that each “Frame” is rendered and available, so that frame-accurate editing is possible. The NLE will not need to do any processing, or conversion of these files, as even the Audio is ready for DVD-Video. Note: there will still be Conforming and the generation of PEK (Waveform Display) files, but the NLE will be able to do this quickly and efficiently.
    Using AVI Uncompressed will get you nothing that you can see, other than larger files. Do NOT use any compressed format/CODEC, like MPEG-2, WMV, MOV, etc., as these will loose data from an already inferior source, and will then need conversion to be used, either with a stand-alone conversion program, or internally by the NLE. You loose quality and then have more work to be done. Do not let the temptation of smaller files lure you into using anything but DV-AVI Type II, and just accommodate the larger file sizes.
    With the file format/CODEC decision made, the cables and devices hooked up, we’re ready to start the Capture. The exact operation will depend on what our equipment choice has been. See above for talk about additional Capture software, if one uses a capture card. Otherwise, we should be able to use the Capture module of our NLE. The first issue is that we will NOT have Device Control, as we would with a Capture from a miniDV tape-based digital camera, where we can control the mechanical aspects of the camera, during this process. As our VHS deck is hooked up to the A-D bridge, or digital camera w/ pass-through, via analog cables, our control signals cannot be sent to it. One would cue up the tape in the VHS deck, and then choose Record/Capture in the NLE’s Capture module, starting the Capture. Instantly, they would hit Play on the VHS deck, or via that deck’s remote control. This is easier the second time that one does it. I sit with the mouse in my right hand, poised over the Record/Capture button, and the VHS deck’s remote in my left hand, finger hovering over Play. It’s then a 1 - 2 push, and all starts. One can stop the Capture, if an unwanted section of tape comes up. The Capture module of the NLE will direct us on how to proceed from there, should more Captures be wanted. Some will just start up at a later point, and write an additional file for that portion of the tape, but some might require that one basically sets up a new Capture session One should investigate just what their NLE will require for doing multiple Capture sessions from one VHS tape.
    When done, one closes the Capture module, and then navigates to the location that these DV-AVI Type II files have been stored in, and Imports them into the Project. This differs slightly from doing the Capture from a miniDV tape camera, as those Captured files are already in the Project.
    Edit away, and Export/Share to the necessary output settings, file type and CODEC.
    What about those VHS - DVD decks, the ones that will burn a DVD directly from the VHS tape? They seem so simple to use, and for the most part are. However, those DVD-Video discs, contain pretty heavily-compressed MPEG-2 AV streams. These MPEG-2's, besides being compressed, are in aGOP structure and are muxed (Multiplexed into one file with both a Video & Audio stream), plus there is often some Menus and navigation in the first VOB, the main container components of a DVD-Video. Many NLE’s can Import the VOB’s, and basically rip the MPEG-2 out of them, but that first VOB can be highly problematic, due to the way that most of those decks do the Menus and navigation. It is seldom 100% DVD-compliant by the DVD-specs. This can be a major problem. This ARTICLE will give you some background and tips on DVD VOB's.
    Those dual-decks are good for doing one thing, regarding the DVD’s that they produce - provide one with an archival DVD-Video of the VHS tape, and not to be edited. However, the VHS side of these works well with an A-D bridge, just like a pure VHS deck does. I would strongly recommend that one does NOT use the DVD-Video portion of these, if editing will be desired. They cause many more problems, than they solve - just use them for an “archive” copy of the tape to a DVD-Video, for playback on a computer via DVD software or a set-top player, hooked to a TV.
    What about film? Well, film is obviously analog, and one needs to digitize this to edit on the computer. The process of this digitizing is referred to as telecineing the film. While one can buy equipment to do this, it is expensive, and involves a lot of setup and testing to get the job done. There are many service bureaus, that offer telecining. Some are better than others. The main considerations are: care in handling of fragile film, how the telecining is done, i.e. frame by frame w/ a liquid gate, or just by straight projection, and then output format for the digitized files. Some of these services will offer a DVD-Video disc. Do not be tempted to do this. See above. Others will offer to write these digitized files to a miniDV tape, and this is just fine. One does then need a miniDV camera, or miniDV tape deck, to then do the Capture from, but the quality and editability will be preserved. The final delivery format would be to put these DV-AVI Type II files onto an external HDD. This saves one from having to do the Capture from miniDV tape, having to have a miniDV camera, or miniDV deck, and only Importing of those files would be required to get them into the Project. Many of these service bureaus will either sell you the external, or use one provided to them. Check out specifications for things like format of the external. FAT-32 will limit the file sizes to ~ 4GB max, and NTSF will have no such limitations. However, if the service bureau is on Mac, and you’re on the PC, their Mac’s can ONLY see FAT-32 HDD’s. Talk this over with the service bureau first, so that there are no surprises later on.
    Hope that this helps,

    Although I now have a Canopus ADVC300 I previously used a Magix 'Movies on DVD' USB device. I found the results from this to be particularly good and, to my ageing eyes, I see very little quality difference.
    I think this is because Magix use their proprietary high quality codec (from their Pro products) to capture the footage. Like DV-AVI it runs around 10GB+ per hour. This can then, very simply, be exported to DV-AVI Type 2 for use in PRE. Note that there are some sound synchronisation issues with the 'out of the box' settings - but the fix is quick and I posted details to the Magix forum.
    Would I revert if I could return my ADVC300 bridge? Probably not - the firewire connection and the PC seeing the box as a camcorder adds to ease of use. In fact I am pleased to have both. There are some things Magix does better than PRE7 (batch exporting each scene as an individual DV-AVI file being just one) and it has smart-rendering which is handy for quick clip splitting/exporting.

  • Converting analog 5.1 (multiple cables) to Digital DIN (for Inspire 5700), how?

    Hi,
    So far I've been using my Inspire 5.1 Digital 5700 speaker system together with my Audigy Platinum in my Desktop PC to watch DVDs and play games with a 5.1 experience. To connect soundcard and Speaker system, I used the provided Digital DIN cable, and it worked fantastically, for both, DVDs and games.
    Now I bought a notebook and the only choice to improve onboard sound was the X-Fi Xtreme Audio Notebook. I thought that I could simply connect it to my Inspire 5700 by connecting optical out with optical in using a TosLink-Mini -> Toslink cable. While this may work for DVDs (I don't have the cable yet), it won't work for all other applications, because as I read optical connections only provide a stereo signal unless the signal it'ss encoded via AC3 or DTS.
    Of course there is the docking module which provides multichannel analog out. Trouble here: the Inspire 5700 only comes with two analog line in channels, front and rear. So that would lead to 4.0 instead of 5.1. Missing the center speaker for games is very bad.
    Therefore I am looking for a way to convert the analog signal coming from the docking module into something that can be decoded as a 5.1 signal by the Inspire 5700. I have already found the DTS-610 which would turn the analog signal into a DTS signal. But that costs more than the soundcard itself.
    So, my question: Is there any simpler / cheaper way how to transform multicable analog 5.1 to one-cable digital 5.1, either AC3, DTS or Digital DIN? I'd prefer a simple converter to Digital DIN, because that's what the Inspire 5700 was mainly designed for and it worked perfectly with my old Audigy.
    Alternatively, one could possibly also use some fancy software to convert all the wave-out sound into AC3 or DTS and send it along the optical cable. But I don?t know any such software plus I expect this to drain a lot of processor power.
    Any help is greatly appreciated it'ss kind of frustrating that two products of the same company can't be connected with each other, just because neither, the card nor the docking module provide Digital DIN.
    Thank you very much and best regards

    P.S. in another post, pjc said: You will probably require a 4-pole mini-jack > DIN converter to connect your Creative speakers to this socket.
    That's exactly what I'm looking for, but I couldn't find such a converter on the creative homepage.

    I believe the DIN for soundcard are mainly built and solely used by Creative. I don't think there is any 3rd-party converter in the market to do DIN. There is a software here posted by some other users that can do AC3 encoding on the fly. Not too sure where's the post now but you can do a search for it.

    That?s exactly what I?m looking for, but I couldn?t find such a converter on the creative homepage.

    I finally got the Toslink -> Toslink-Mini cable which I need for optical out. Well, as you said, there is only stereo, so that's no big news. I was quite surprised to see, however, that the Xtreme Audio Notebook card cannot even pass an AC3 signal from a DVD to the receiver. It can provide stereo for DVDs, but once I choose S/PDIF out (in WinDVD), there is no sound at all. If, however, I simply pull out this useless card and plug the cable directly into the the S/PDIF of my notebook, I get wonderful DVD sound in Dolby Digital. So, what the heck is wrong now? It says "Dolby Digital" and DTS on the box, so I guess it should work. Why does it work with onboard audio but not with the external card? It's really kind of disappointing, since I bought the card to have surround in games and to be able to watch DVDs in Dolby Digital. The card can do neither of it, unless I'm doing something wrong.
    Any hints are welcome, and thank you for your explanations so far!

  • Convert Analog 14V signal to a boolean

    Hi all, 
    I'm trying to use a proximity sensor (Panasonic GX-F/H) which switches between 0 and 14V to stop a linear motor. What is the proper way to convert the analog input singal from the sensor into a boolean? 
    My attempt was to connect the sensor to the analog input of my DAQ 6008 and use a comparator (signal < 10V) --> see attachement. This actually worked but it sometimes had a delay of more than 1s, what makes it impossible to position the motor accurately. Any ideas to solve this problem? Thanks in advance!!

    I need to import a live analog RCA signal into a Macbook Air 13" model A1466 to record on Final Cut. Is this possible? If so, what equipment/cables do you recommend pruchasing?

    If you want audio and video from your RCA cable source, you would need a converter device. One that I have used is the EyeTV Hybrid from ElGato. You attach to the Mac via USB, and can attach to RCA composite, Coax, or S-Video. You would record into the EyeTV software and later export to Final Cut for editing. This would not go live into Final Cut Pro.

  • Scb-68 and PCI-8331 what is converting my analog sgnal into digital%3F

    Long ago, around 7 years ago, I worked on a project in which I interface photodetector to my computer through SCB-68 kit. The SCB-68 kit was connected to computer using PCI-8331 card.
    Now, my input was analog signal from photodetector but at programming interface I was getting digital values for computation. Now my confusion about the conversion task done by which part of this connection?
    SCB-68 was converting the input signal and supplying digital output? or PCI-8331 was doing digitization before delivering information to computer? or labview itself was doing it after getting signal from PCI-8331?
    can anyone please clear me?
    Thanks!
    Solved!
    Go to Solution.

    The scb-68 is just a dumb terminal block. The pci-8331 is http://sine.ni.com/nips/cds/view/p/lang/en/nid/13179 and does not connect to photodetectors so your memory is flawed about the part number. An actual DAQ card would have done the conversion.
