Window
Blackman
This is the best window for measuring the amplitude of
frequencies but worst at resolving frequencies.
Use Blackman-Harris for measuring predominantly
single frequency waveforms to look for higher order
harmonics.
The pictures show four kinds of window function referring to sine wave of 1kHz
