Hello
I have a mixed frequency signal with a lot of noise. I plotted the spectrum of the signal using fft and also plotted the psd of the signal using the sp tool. I don't quite see the peak of the signal in fft plot althought the psd plot shows a peak and then rolls off. I don't know if i am missing to interpret something in the fft plot? I can attach the plots but don't know how. Thanks.
