Hi, I'd like to plot phase difference between two signal(input-output), the method which I'm using currently, is taking "FFT" and (r-teta)....and subtracting the phases, but what I obtain isn't so desirable, Do you know anyother option or suggestion to make my results better? I've attached the plot and marked them, one of the is "Output FFT- magnitiude vs. Frequency" as you see it's acceptable, but another which is "phase difference vs. freq" isn't so good.:( Thanks Petar

here is a short play around with phase unwrap a groupdelay of >1s ???? What and how are you measuring???? Can't open your code... still stick to an old version here

Phase difference

Solved!

I think you should do it while the program is closed. Go directly to the folder and then make the zip file.
