I think I've solved my own problem. The problem was the bizarre way MATLAB does FFT. I redid it with the following: L=100000; Fs=###; w_filter=[-L/2:L/2-1]*Fs/L; % have to evaluate the function from -Fs/2:Fs/2-1 Z_lowpass = 1./ (1 + iw_filter*RC); signal= ones(1,100000)...

Got a DSP problem. I think this is a bit complicated, and may need some DSP gurus to answer it. I've been banging my head on this literally for months now. Thought I had it figured out, but today find I'm still not done. I have some Impedance spectroscopy data from electrodes, sampled at...
