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?

  • How to get rid of the notifications center from the menu?

    I unchecked all the "in notifications center" boxes so there is nothing in there. But the notifications center icon is still up there on the menu, over on the right side.
    Is there a way to just get rid of it completely?
    Thanks,
    doug

    From the OS X Finder, hit Command+Shift+G and enter the path to /System/Library/CoreServices/
    Locate “Notification Center.app” and click on the name to rename it to “Notification Center-disabled.app”, authenticate the change when prompted
    Now launch Terminal, found in /Applications/Utilities/ and type the following command:
    killall NotificationCenterQuit out of Terminal
    Notifications will no longer be posted, alerts will be gone, and the menu bar icon is no longer visible. If you do attempt to get to Notification Center either through a keyboard shortcut or the sideways swipe, you’ll be presented with a blank side of the screen.

  • How to get rid of the DC offset?

    Hello everyone,
    I use USB6211 to control a power supply (PS375 SRS) through a wire lead BNC cable.
    The problem is that when I sets 0V on "Gen Voltage Update.vi", the monitor of PS375 showes 9-13V offset on its numeric display for output voltage.
    When I want to set 100V, then the display showes 109-113V.
    I found that
    1. When I shutdown the PC, the PS375's numeric display showed 0V
    2. When I turn on the PC, the PS375's numeric display showed 9-13V
    These are the all information I have.
    Could you help me?

    That SRS unit is a 20KV supply, correct?
    0-10V in = 0-20KV out. You are seeing a 10V output offset, that translates to 5mV input offset.
    If you have a DMM or scope, monitor the DAQ output when connected to the SRS to see if there is any DC and AC components when the DAQ is set to 0V output.
    That fact that you see an output offset when the PC is turned on leads me to think it could be noise on the 5V PC power supply.
    Have your tried using the RS-232 port for programming the SRS? This may be more accurate than using an analog control voltage.

  • HOw to get rid of the borderline in the  render list item of the news brows

    HI,
    HOw to get rid of the renderlist
    border line,
    Give Feedback  link   
    Send To  link in the news browser.
    After removing thiese things, it should look like a normal html page .
    how to  achive this ,
    if coding required then which is the par file I need to modify
    thanks
    pkiran

    Hi PKG,
    the "GiveFeedback" and "SendTo" links are called "FlexUI" commands. Most of that stuff is highly configurable and naturally you can remove them in the KM Configuration at
    SystemAdmin->SystemConfig->KM->CM->UserInterface
    -> ... -> ResourceRnderer
    Your ResourceRenderer uses a CommandGroup. In this CommandGroup you can add/remove commands.
    For example un your case its the CommandGroup "NewsDisplayGroup"
    Kind Regards

  • How to get rid of the Login page in Portal?

    Hi Guys,
    I have a newly developed intranet portal project for my company which does not need login no more. I hope you can help me how to get rid of the login page in portal which is I know in every application you create, there should be a login. Is this possible that I can just simply type in to the URL address bar my application then it will no longer ask for any logins? Please help! Many thanks!
    Russel

    Hi Russel,
    You can give public access to pages, applications etc. Users won't need to supply a username/password then, while you still can hide some of the pages to authorized people.
    Check the access tab for pages and the manage tab for applications.

  • How to get rid of the black border around the artboard

    Hopefully my last question for tonight.
    I need to get rid of the black border around the artboard. The two images show my drawing lined up with the art board and then inside the artboard. The dark gray is not the artboard.
    As you see, the artboard has a black border. I need to get rid of it. It shows up in my project when my color key is green. The black won't go to transparent.
    So how-to get rid of the border? Thanks
    ***Update***
    I figured it out. View > Hide Artboards. Maybe this will help someone. Doesn't change the fact my spider looks like a tick:)

  • How to get rid of the "time out" when using DAQ AI in the example program

    I try an example file called "AcqVoltageSamples_IntClkDigRef" (Visual C++ .NET). It works great. However, if the program has not recieved the data, it sent out a timeout message. How to get rid of the "time out"? I cannot find anywhere in the code. Is this a property I have to reset somewhere else?
    Thank you,
    Yajai.

    Hello Yajai,
    The example program will use the default value for timeout, 10 seconds. To change this, you will have to set the Stream.Timeout value. I inserted this function into the example and set it equal to -1, and the program will wait indefinitely for the trigger signal without timing out. Please see the attached image to how this was implemented.
    I hope this help. Let me know if you have any further questions.
    Regards,
    Sean C.

  • How to get rid of the main text box in the back of the page AND move things

    I usually work in Adobe Illustrator, Photoshop, and InDesign, but am creating two newsletter templates in Pages for a colleague, since it will be easier for her. But, for the life of me, I can't figure out how to get rid of the main text box in the back of the page that is driving me crazy. I just want a nice blank page that I can do whatever I want with. AND, I can't figure out how to select things so that I can move them, like shapes and text boxes. Some things seem to move fine, then other things just sit there. I am at the end of my rope!!!

    Hi, Dylan. Welcome to Discussions.
    If you're referring to the area where you just start typing when you open a new blank document, you can't get rid of it. But you also don't have to use it. You can insert text boxes and size and position them as you desire. Just be sure they're defined as Fixed on Page. When one is full and you want to continue it to another page (or to the side), click in the blank blue box on the lower right side of the text box. That will create another box and your overflow text will flow into it. Then position it where needed.
    Also, you can create a text box the width of the page and then set it for 2 or more columns.
    When you want to send something to the back and you may want to access it again later, just use the send backward command. If you send it all the way to the back, it will be behind the main text layer (where it will be safe from acvcidental movement) but you will have to click outside the work area and then drag the pointer to the object to select it.
    Hope this helps to get you started.

  • How to Get Rid of the Extra cents left on your gift Card balance?

    I would very much like some help on how to get rid of the 65 cents I have left in my itunes account, without having to spend it on something, or make a new account, or contact Apple. Please someone help with this, I'm sure many other are having trouble as well!!!!

    I noticed there is an extension which lets you clear the title of the current page or replace it with other text. This seems to work equally well in private and non-private windows, however, it doesn't appear to have an option to automatically do it in all private windows. Maybe someone can add that feature (the author isn't maintaining the add-on any more).
