2. 5 Window Types Used in FFT Functions

Option
Rectangular Simplest B-spine window
Bartlett
Hanning
Hamming
Blackman
Kaiser
Gauss
22
Description
Hybrid window
Side-lobes roll off about 18 dB per octave
Optimized to minimize the maximum nearest side lobe
Higher-order generalized cosine windows for applic-
ations that require windowing by the convolution in the
frequency-domain
Adjustable window maximizing energy concentration in
the main lobe
Adjustable window (can be used for quadratic inter-
polation in frequency estimation)
