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
I didn't say it affects the signal power, just wanted to make sure if you've taken it into consideration or not while calculating the power. If you're sure it's right then I can't offer anything else to check other than debuging a very simple case with just 'fft', 'ifft' and power calculation functions.
