Steps for designing FIR filters

Question

Explain some of the steps which are included within design of the FIR filter.

Answer 1

The steps for designing the FIR filter can be explained as:

a) Decide the required frequency response Hd(w).

b) Take inverse Fourier transform and get the Hd(n).

c) Transform the infinite duration sequence from Hd(n) to h(n).

d) Acquire the Z transform of the h (n) to get H(Z).
