Hi, I compute the cross spectrum, using the CSD function, and I am trying to represent it in time-domain using IFFT (see example below). But what I got in the y-axis is something strange or maybe not-normalized. Does anybody have tried it before ? How can I perfeclty represent the power spectrum in time-domain ?? Example: x = csd(signal); plot(x); y = ifft(x); plot(abs(y)); cheers, Noriaki |
