Exp 8 : Digital FIR Filter Design using Frequency Sampling Method

For this experiment we used frequency sampling method in order to design the filter. In this method, H(K) is obtained by replacing w=6.28K/N in Hd(w) & by simply applying IDFT to H(k) we can obtain h(n).
We designed LPF & BPF for specified As,Ap,Fp,Fs & Fsamp values. After doing calculations on values derived from magnitude response we obtained As & Ap values. (calculated).

The code was run on Scilab and graph was plotted. The phase response linearly varies with frequency.
