hi,
i wanna do the fft analysis of n matlab, assume fs is the sample frequency, f0 is the fundamental signal freq,and i have got N samples loaded in matlab, then how can i decide whether to use window or not? how to select the number of fft points? will the number of points affect the fft results?
and if possible, can anyone give me some matlab code for testing dynamic characteristics of a adc?
thanks a lot
