What sort of windows do folks use for making FFT measurements of phase
Say you have 1 second of sampled data (so the FFT resolution is 1 Hz).
If you're interested in the noise power at, say, 10 Hz away, a
rectangular window isn't going to be very far down, unless you have a
LOT of points in the FFT.
Grove's paper from 2004 doesn't mention this detail.
