Edit Question
Title
Body
I am using the FFT function in NumPy to do some signal processing. I have array called signal which has one data point for each hour and has a total of 576 data points. I use the following code on signal to look at its fourier transform. t = len(signal) ft = fft(signal,n=t) mgft=abs(ft) plot(mgft[0:t/2+1]) I see two peaks but I am unsure as to what the units of the x axis are i.e., how they map onto hours? Any help would be appreciated.
