This whitepaper presents a new perspective on decimation and interpolation filters. It presents a brief introduction and historical perspective on these filters, as well as the audibility of signal ...
As a parting shot, I pointed out that there are three quadratic terms there with unity coefficients of z 0 – and there are three deep nulls in the filter’s gain response, as was shown in the figures ...
The design of finite impulse response (FIR) filters remains a cornerstone of digital signal processing, with ongoing efforts to refine both the algorithmic and hardware aspects of their implementation ...
