WebOct 1, 2013 · I have a noisy signal recorded with 500Hz as a 1d- array. My high-frequency should cut off with 20Hz and my low-frequency with 10Hz. What I have tried is: fft=scipy.fft (signal) bp=fft [:] for i in range (len (bp)): if not 10<20: bp [i]=0 ibp=scipy.ifft (bp) What I get now are complex numbers. So something must be wrong.
