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 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.
What Is PXI?
To configure a complete PXI System please go to: Build Your PXI System -
How can i change analog waves into digital waves?
we had labview lab last week.. were doing fine if we have instructions unfortunately the professor will give us an exercise regarding baseband signals spectra.. were trying to download a trial software but we dont have any luck. the question asks for us to change analog waves into digital waves, measure the amplitude of the 5-th harmonic using spectrum analyzer.. i hope you can help me thnx..
After you are successful getting LabVIEW on your computer, put together something to at least show us you're up for learning. Then we can guide you to a solution that you've developed (mostly) on your own.

I am trying to convert Analog video to digital to my Macbook for work, and every time I run it through my converter the audio De-syncs about halfway into the video. Does anyone know how to go about fixing this issue or have had similar issues to this? I have no issues when converting to my PC, but only my Mac. Thanks!
Hi Rick,
I am extracting the material from the dvd directly using handbrake. The file that handbrake creates lands on the desktop. I then ammend the end of the filename from mp4 to m4v. Following this I click and drag the file onto the itunes icon in the dock. I can then download it to the ipod no problem. The dropouts occur no matter where I play the file. In other words, on the desktop (with QT), in the itunes library and on the pod.
I went back and looked at all the dvd's that are giving me this trouble. The culprit seems to be that the audio signal is in LPCM (linear pulse code modulation). Just for the **** of it, I tried to rip one track using handbrake changing the sampling rate of the audio to 48,000 Hz which I believe is what LPCM uses (previously I had set it at 41,000 Hz in handbrake). But no go, still has dropouts. One of these problem dvd's has a second audio option in AC3 (2ch). As a test, I ripped one song using that. Dropouts are gone. However, the audio is a director's commentary (on the music video he shot) with the music in the background, so it's not what I want.
Is there any way to convert LPCM to AC3? Or any other way to fix this dropout problem.
Thanks,

How to convert DataServices.Result into an Arraylist or ArrayCollection?
I want to use an ArrayCollection or an ArrayList as a data provider
for a dataGrid, and then later in a Graph.
The problem is that the starting point is the FLEX Builder 4 created "datasource.lastResult" value Objects.
I don't know how to access anything but the Column names.
The fields returned are:
gmtdate,hostname,CPUBusy
I want to show CPU busy for "N" number of hosts.
So I need to change my result from the SQL query in Action Script into:
gmtdate, hostname1_CPUbusy, hostname2_CPUbusy, hostnameN_CPUbusy
Are there any samples of how to convert the .lastResult into an ArrayList?
The result set is Object based and I can't figure out how to read it.
Thanks,
DavidI wish I could change it, but Oracle SQL does not allow for an unknown number of hosts.
Nor does this version of Oracle have the new pivot function.

How to convert jpeg files into Word
Hi Eugene,
I don't think you can convert an image to a Word document, but you could place the JPEG into a Word document using the Insert > Object command in Word.
For other questions relating to Word, you will probably have more luck getting an answer if you post on the Microsoft forums (we can help if you're using Acrobat, or another Adobe product, but you'll find the Word experts on the Microsoft forums.)
