Hello, Not sure if this is the appropriate forum for this, but I'll give it a shot. I am recording a laser signal through my experiment which is running an FM scan at 20 kHz. The time scale of the experiment I'm running is much larger than the 20 kHz signal, so each scan is about the same. In the end I get a data signal file (through my DAQ) which has around 100 repetitions of this scan. I am wondering if anyone knows of any type of software or Matlab routine which could interpret and average the repeating waveform for me. Each particular waveform may have a bit of noise affecting the sample, but when averaged with the others this should drop out (to a respectable degree). Any help would be greatly appreciated, thanks!
