They are all already implemented in scipy.signal.windows, see source code.


T=0 or T=infinity. Any non-zero signal with finite length support in one domain has infinite support in the other domain. cos(wt) is only theoretically band-limited if infinite in length.


Currently, I find my impulse response by performing an FFT of size 32k on my entire measurement signal, and my reference signal. I divide each by the scaling factor 1/sqrt(M) Scaling here is unnecessary since you are going to divide the two spectra anyway. Any scale factor will cancel out. I then divide the two signals, and perform an inverse FFT, ...
