Xander Posted May 9, 2006 Report Share Posted May 9, 2006 Dear members. First I want to say I've learned alot on this forum. There are a lot of members with good knowledge about Labview. I like this forum very much and want to thank you for your help you are giving members. Please keep up the good work! My problem is as follows. I want to analyse a sine which is brought in through the audio line in on mijn soundcard. I've written a labview program which opens the audio line in and I can view the input "realtime" from the "si read.vi" VI. My signal consists of a single sine which stabilizes to zero in a period of time (say, 10ms). I would like to acquire this sine in a waveform chart so i can scroll left and right to view the sine. Next thing I would like to determine the maximum amplitude and at which X coordination it's happening. Next I would like to determine the first zero cross time of the first half period of this sine. Is there someone who can help me or give me a push in the right direction? I appreciate it alot, thanks in advance! I've added a picture for illustration. Quote Link to comment
