Remove dc offset from a signal

Hi! i need some help with removing the dc offset in my signal. Is there any labview function that i am able to use to remove the dc offset from my spectrum? I have seen some question asked in the forum but i cant really understand what they are saying. I really need help! Here is what i have done.

Hi GG,
did you read the error message? It clearly says: "trying to connect a cluster to an array of cluster"...
You use express VIs with their DDT (dynamic datatype). When using "real" datatypes the function "FFT power spectrum" just outputs a single spectrum (instead of the array before)...
Best regards,

Kudos are welcome

  • Removing printer offsets from PDF pages

    I accidently set up a printer page offset when creating PDF pages from Word Perfect X3. Is there a way to remove the offset, or do I need to go back to the original WP pages (which I can't find!)?

    I recreated a page and made sure there were no offsets listed. The PDF page still prints offset. I found sources to recreate the page, displayed codes, and removed anything marked as offset. There is still an offset to the left when pre-print displaying either the source page or the PDF version.

  • How to get rid of the DC-offset from a signal?

    Hello
    i have a speech signal which i need to process. I have estimated its DC-offset (using the AC-DC estimate vi) to be approximately 126 V. I have read some posts here that some reccomend to just subtract this value from the array of data or use a filter to do it. What is the difference, which one should perform better? I have also broke down my initial array of 50000 samples into sub-arrays of 512. Where should be the best place to get rid of the DC? Once and out from the initial array or later on from the subarrays?
    When someone says subtact that value (DC value) from the signal, what exactly has to be done?
    When using a filter, what shall i be looking for to do?Specifications of it?
    Any help is appreciated

    Hello Lynn
    So you are just saying, get the DC offset since it stays almost constant, from the AC/DC Estimate VI and just subtract it from my initial array at the beginning once and out and further on move with the rest of my process? That's it as it shows in the pic below?

  • I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

    It's almost impossible.  The new iMacs have a Target Display Mode, but it's built to do that.  Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15.  In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
    By the way, I found your answer by searching this forum.  I would suggest using the search function here in the futuere.

  • Remove DC component from Zoom FFT

    I am performing vibration analysis using the sound and vibration toolkit. Is it possible to remove the dc component of a frequency domain signal generated from a Zoom FFT? Or remove the DC component in the time domain signal prior to performing the Zoom FFT?
    Thanks

    You might consider a high pass filter on the data prior to the FFT operation.  THis would in effect AC couple the signal - removing the DC component.  You could also use the AC/DC estimator and subtract the DC result from your signal.

  • Removing camera flash from video

    Is there a way to remove camera flash from video clips within PE8?  If not natively, is there a plugin that can do this?
    Thanks,
    Steve

    Here are the best answers that I can offer:
    1) why do you go from Premiere Pro to Premiere Elements?
    Actually, about 90% of my work is in PrPro. The rest is in AfterEffects, PrE and other NLE programs. Basically, I use those, including PrE, when they do something better than PrPro. PrE will accept a broader range of formats/CODEC's, than will PrPro, so I use it to Import those odd Assets, and get them ready for PrPro. Same with CyberLink's PowerDirector, and Magix MovieEdit Pro.
    2) How do you synch the audio and video  (I'm guessing that you record off-camera).  I synch it by eye and ear and it can be tedious.  I don't have time code synchronized equipment
    Most of my shooting is actually done with camera audio capture, though usually through either a shotgun, or wireless mics, attached to and recording to the camera's tape. When I do separate audio & video capture, I slate, so that I have the visual and audio sync. When I am faced with having to do manual sync, I will look for the visual and then the accompanying audio, and just nudge and listen. This ARTICLE will give you some of the mechanics of the process.
    3) I don't know much about DD 5.1 SS and this is just from the point of curiosity at present, can it be a problem keeping long clips in sync?
    I do not record to DD 5.1 SS, as that is a very expensive and technically challenging process. It takes six well-designed and well-placed mics, a multi-channel recorder and a mixing panel, run by a skilled tech. My DD 5.1 SS Audio is with regard to the music for my Projects. Some of it is recorded as 6 discrete channels and then mixed, while some is faux 5.1 and is "created" from 2-channel source material.
    Much of the work from Hollywood is actually faux 5.1, in that the source material is seldom recorded in 5.1. Most is stereo and mono, and is blended from myriad sources. These can be SFX, dialog, ambient audio. Most of those are mono TO separate them out from any other audio sources. Narration is a good example. Few audio techs, would consider using a stereo mic for narration and would choose a very directional mono mic, so as to better reject other audio signals.
    Now, I can take a mono SFX file and pan/fade (not in the terms of a "fade" Transition, but front to rear location) it across/around the sound stage. I can place that bumblebee anywhere that I want, when I want it with 5.1 SS Audio. I'd almost always work with mono sources, so that I have the pure signal with no clues as to the source location - I set those in mixing.
    I must add that with regard to mixing of music, there are constraints on doing faux 5.1. If the material was not recorded on multiple tracks to begin with, the RIAA, and other organizations, greatly frowns on creating a 5.1 "master." That came after the failed quadrophonics experiments from the '70s/'80s. With Hollywood's music, the recording IS done multi-track in the studio/symphony hall, so it IS multi-track and just gets mixed down to 5.1 Audio. This will be about the only time that the audio is done multi-channel in recording, as few environments lend themselves to doing 5.1 during the initial recording. There are exceptions, like live concerts, but that is almost a genre unto itself.
    Sync, in and of itself, is not difficult to maintain, but so much depends on the recording equipment. Many, using separate cameras and recorders, often find that there is sync drift, and need to establish the % of "cure." In the old cine days, we hooked our camera to the Nagra recorder, and chose which unit's crystal clock would establish sync. Then, we had a cable between the two. Nowadays with digital, it seems a bit more difficult. There are several recent threads in the PrPro forum about the sync drift between pro-level cameras and recorders. One user has found that altering his recorder's output by 104% fixes the OOS issues. Others need to test critically. The sync clocks in different equipment just does not match up perfectly, and there is usually no universal crystal clock that overrides the internal ones - like in the "good old days."
    Hope that this helps. If I missed something, please let me know,
    Hunt

    how do I remove a network from airport please?

    What is it you are trying to do? Your Airport will recognize and list any WiFi signal within its range. If your preferred network list doesn't include the network you are trying to remove it will just ignore it. If it is on your list just highlight the network and click the " - " button.

  • Anyone know how to remove Overdrive books from my iphone that have been transferred from my computer? They do not show up on itunes. I see a lot of answers to this question but they all are based on being able to see the books in iTunes.

    How do I remove Overdrive books from the library that were downloaded onto my computer then transferred to my iphone? The problem is that they do not show up in iTunes.
    I see this question asked a lot when I google, but they always give answers that assumes you can find the books in iTunes either under the books tab, or the audio books tab or in the music. They do not show up anywhere for me. They do not remove from the app like the ones I downloaded directly onto my iphone.the related archived article does not answer it either.  I even asked a guy working at an apple store and he could not help either.   Anybody...?
    Thanks!
