Hello,
How can I calculate the Fourier transform of impulse response ^h(w) and phase function psi(w) of the given impulse response h= (kh) is defined by: h0= 1/2, h1= 1, h2= 1/2, otherwise= 0 ?
Thanks for your help.

The complex transfer function [FIR filter...] is easily obtained from (1) setting . A more complex alternative is the derivation of the H(z) fron the H(k) I have defined in my previous post using the inverse discrete Fourier transform...

... and again You can find the complex transfer function setting in (2) ...
Kind regards
