Editor’s note: I came across this excellent tutorial article on Digital Filter Design and I thought it would be an excellent guide for novices as well as seasoned veterans. I want to thank William H.
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 has evolved into a sophisticated discipline that balances signal-processing performance with hardware efficiency. Innovations in FIR filter design ...
