i design the notch filter by using hilbert transform. My problem is that i am not able to vary the frequency so that i can get a notch filter that can remove frequencies on demand?

[h2d,w2,w3] = freqz2(h ,length(m),length(n)); %f1 = fftshift(h,128) Hilbert2DMag = abs(h2d); Hilbert2DPhas = angle((h2d)); subplot(3,3,3) [w2,w3] = meshgrid(-pi:pi/10:pi); mesh(w2/pi,w3/pi,Hilbert2DMag)
subplot(3,3,4) mesh(w2/pi,w3/pi,Hilbert2DPhas)
