- dft - Understanding Polyphase Filter Banks - Signal Processing Stack . . .
In the simple example above the top filter bank is from coefficients 0 and 4, while the next filter bank is the coefficients 1 and 5, and thus will have the same frequency response delayed by one sample (with the only difference besides that time delay through the filter being the effects of the aliasing) as diagrammed in the example frequency
