I would like to convert a continuous waveform (created in Labview with the waveform generator vi) into digital form...am I on the right track (see below)

I would like to simulate a sample and hold circuit. I was thinking of using the zero order hold vi (for continuous to discrete conversion) in combination with the AC to DC vi? Am I on the right track, or could anyone suggest a better way to do this? Many thanks in advance! 

Hi,
The answer to this question was answered in the forum post below:

    The new Mac's do not have analog audio in so you will have to go with a USB audio in device or else if you do not yet own a turntable (or are looking to upgrade) you could get a turntable that has USB out.
    The Griffin Technology iMic USB Audio Device is a low cost consumer grade solution if you already have a turntable.
    For recording I use Audacity: Free Audio Editor and Recorder which does a good job and has the ability to run the audio signal through various filters.

  • I have a music video I would like to convert into music

    I have a music "video" which is just plain music with a picture. I would like to convert it to just a sound file for my Ipod.
    Can someone give this hopeless noob some pointers?

    I don't know the diffs between the QT versions on different platforms and the export option may be a pro feature. I've use QT Pro for all kinds of things. After one upgrades you can't tell which features are Pro so I can't help you there. If you want to just make a smaller video iTunes will let you generate an iPhone or iPod copy of a video which is slightly smaller. Check the right-click menu on a song in the library.
    I haven't checked, but I wonder if GarageBand or iMovie would do this as well. Hmm, something for me to do today.

  • I have a Canon 6d and would like to convert my raw ( CR2) photo's into dng files. Adobe DNG converter 8.4 doesn't recognise the CR2 files. How can i solve this?

    i have a Canon 6d and would like to convert my raw ( CR2) photo's into dng files. Adobe DNG converter 8.4 doesn't recognise the CR2 files. How can i solve this?

    It is possible that you are not following instructions correctly in the DNG converter. The DNG converter interface asks for the FOLDER that contains your raw images. Choose the folder, but don't open it. After you have chosen the folder, click on the Convert button. The DNG conversion process should start.  Does that help you?

  • How do I open my old Appleworks documents which have turned into Unix Executable Files?  I would like to convert them into Pages documents.

    How do I open my old Appleworks documents which have turned into Unix Executable Files?  I would like to convert them into Pages documents.  I also have old Word Perfect documents which have become similarly unopenable.

    Best bet might be to try opening them using LibreOffice [free] and save them to .doc.
    Do you really want to save them as .pages files? You are jumping from the frypan into the fire. Yet another proprietary format that Apple has again deadended with no working translation.

    Would Like to Get Report of Daily Emails In and Out from Members to a DL
    Exchange version : 2007
    I am the supervisor for the group and want to quantify this information. I do not need to see the content, just quantity
    is it possible ?

    Well, distribution groups don't really have a concept of "in" or "out". They only serve to distribute messages sent to them -- unless you're asking to know who was a member of the distribution group at the time a message was sent to the DL.
    Message tracking logs hold the information you want, though. You'd have to look for EXPAND events that reference the distribution group and take the sender's e-mail address from that event. If the DL is a simple one that's not a member of any other groups
    you could also look for RECEIVE events sent to the e-mail address of the group and get the sender's name from that event.
    You can use Powershell extract the rows of data from the logs, but you'll have to write the code to get the data out of those rows and into a format you want. Perhaps LogParser could be useful in place of Powershell?

    Hello lynnettefromsk,
    The article linked below details all of the locations that you may need to change your Apple ID. This process should not affect the state of anything on the device at the time.

  • How do you shuffle the image order when creating a new slideshow in apterture 3?  i would like to do this automatically when creating a new slideshow.  i see how you do it when you just play a slideshow.

    how do you shuffle the image order when creating a new slideshow in apterture 3?  i would like to do this automatically when creating a new slideshow.  i see how you do it with presets when you just play a slideshow, but i don't see an option to randomly shuffle the slide order when you create a new slideshow.  i know you can sort it by different fields, but i want it to be random.  thanks.

    If you want to rearrange images in random order you can try an AppleScript:
    retrieve a list of selected images from Aperture
    shuffe the list properly
    create an album in Aperture and add the images from the list to the album (make sure that the album set to be orederd manually)
    Here  is a sample script that shuffles the selected images and displays them in random order in Full Screen Mode:
    on removeItem(ims, i)
      -- remove the item at position "i" from a list ims
              if ims is {} then return {}
              if (length of ims is 1) then return {}
              if i < 2 then return rest of ims
              if (i = length of ims) then return (items 1 thru (i - 1) of ims)
              if i > (length of ims) then return ims -- should be error?
              return (items 1 thru (i - 1) of ims) & (items (i + 1) thru (length of ims) of ims)
    end removeItem
    on shuffle_items(ims)
      -- shuffle the items of the list "ims" randomly
              local numitems, ims_shuffled, nextrest, nextpick, i
              set numitems to length of ims
              if length of ims < 2 then return ims
              set ims_shuffled to {}
              set nextrest to ims
              repeat until nextrest is {}
                        set i to (random number (numitems - 1)) + 1
                        set nextpick to item i of nextrest
                        set beginning of ims_shuffled to nextpick
                        set numitems to numitems - 1
                        set nextrest to removeItem(nextrest, i)
              end repeat
              return ims_shuffled
    end shuffle_items
    on shuffleIms()
      -- retrieve the selected images from Aperture
      -- and display them in random order in full screen mode
              local imageSel, shuffled, i
              tell application "Aperture"
      activate
                        set imageSel to (get selection)
                        set shuffled to my shuffle_items(imageSel)
                        set fullscreen to true
                        if imageSel is {} then error "Please select some images."
                        repeat with i from 1 to count of shuffled
                                  reveal {item i of shuffled}
      delay 3 -- chnage that to the time you want
                        end repeat
                        set fullscreen to false
                        return shuffled
              end tell
    end shuffleIms
    shuffleIms()
    Some more code snippets to go from here:
    To create an album:
                        tell library 1
                                  if not (exists album "shuffledAlbum") then
      make new album with properties {name:"shuffledAlbum", image version:shuffled}
                                  end if
                        end tell
    And to add the images from the shuffled list to the album:
                        repeat with i from 1 to count of shuffled
                                  duplicate item i of shuffled to album "shuffledAlbum"
                        end repeat

  • I have OSX 10.4.11 and would like to upgrade to Mavericks.  Can I upgrade to Snow Leopard or do I have to climb through all the other OS'?  Thanks.

    I have OSX 10.4.11 and would like to upgrade to Mavericks.  Can I upgrade to Snow Leopard or do I have to climb through all the other OS'?  Thanks.

    Hi, you need 10.6.8 first...
    First you need to research all the problems people are having with the higher OSX versions, & make sure you have a bootable clone of what you have just in case.
    then you must get 10.6, install it & update to 10.6.8 so you have the App Store to buy & download the huge 10.8 Installer.
    Snow Leopard/10.6.x Requirements...
    General requirements
       * Mac computer with an Intel processor
        * 1GB of memory (I say 4GB at least, more if you can afford it)
        * 5GB of available disk space (I say 30GB at least)
        * DVD drive for installation
        * Some features require a compatible Internet service provider; fees may apply.
        * Some features require Apple’s MobileMe service; fees and terms apply.
    Which apps work with Mac OS X 10.6?...
    http://snowleopard.wikidot.com/
    Buy Snow Leopard > http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard

  • I would like to do a program that have one string control and one string indicator, any character that I type in the string control in the same time it will be appear in another string (indicator). How can help me?

    I would like to do a program that have one string control and one string indicator, any character that I type in the string control in the same time it will be appear in another string (indicator). How can help me?

    Why not use an event
    Add a While Loop, inside the loop add the Event Sructure.
    Now in the event structure selecd the String Controls.value change event to
    react
    and the new value inside the event that you get,( connect to the String
    indicator box.

    Here's a quick example I threw together that generates a sort-of-bell-curve shaped data distribution, then performs the binning and plotting.

  • Hi I would like to know, how do I add a Hyperlink on Flash, that opens a PDF in adobe reader and not the web browser.

    Hi I would like to know, how do I add a Hyperlink on Flash, that opens a PDF in adobe reader and not the web browser.

    Yoh, what is FSCCommanr ? sorry man I am an absolute beginner in Flash. I tried the code:
    /* Click to Go to Web Page
    Clicking on the specified symbol instance loads the URL in a new browser window.
    Instructions:
    1. Replace http://www.adobe.com with the desired URL address.
       Keep the quotation marks ("").
    instance_name_here.addEventListener(MouseEvent.CLICK, fl_ClickToGoToWebPage);
    function fl_ClickToGoToWebPage(event:MouseEvent):void {
      navigateToURL(new URLRequest("http://www.adobe.com"), "_blank");
    this is the same code I used before and it opens a pdf file in a web browser, and it doesn't open an AutoCAD file.
