I have a filter whose respose I have in angular frequency.
A0 = [1.0000000,0.3281250,0.0000000]; B0 = [0.5859375,-0.0625000,0.0000000]; [z,p,k]=tf2zp(B0,A0); figure; zplane(z,p); w = 0:(pi/500):pi; H=freqz(B0,A0,w) figure; plot(w,20*log10(abs(H)/max(abs(H))))
1) How can I get the corresponding response in Hertz? Is it:
2) Also, how do I get the response of the above filter, if I apply it to a sinusoidal signal at 20MHz, with a sampling freq of Fs=300MHz
