Window Functions
In the following we will consider some of their characteristics, where we assume N to equal the number
of samples in the DSP Buffer and n to be an integer with 0≤n≤N-1.
Rectangular:
This means the data has no window applied. No shaping is applied to the
incoming signal. As a result, you will have the greatest sensitivity in the power spectrum and
the greatest bleed through or interference with adjacent bins.
