hi all
I'm using the functions(fft,ifft) in a matlab code,theoretically signal power must not be changed before and after transformation according to Parsaval theorem.
But when calculating the signal power before and after using E{X^2},the power of the 2 signals aren't the same.
please can any body helping solving this issue.
Thanks
