I have several files of 118.5 second duration that I would like to calculate the PSD of. I want to do this in 1Hz frequency bins, with Hanning window and 50% overlap, and have considered using pwelch.
First I calibrate the data and then have tried to work out how to use pwelch to no avail so far:
[pxx,f]=pwelch(calxbit, window, 0.5, , 144e3);
How do I specify that I want to use 1Hz bins? My data is sampled at 144kHz.
