dear all , please help me
I design chebyshev II filter using bilinear transformation . (in matlab)
___________________________
% Zero-Pole-Gain design
[z, p, k] = cheby2(n,r,Ws,ftype);
[sos,g]=zp2sos(z,p,k); % Convert ZP2SOS Zero-pole-gain to second-order sections model
h1=dfilt.df2sos(sos,g); % returns a discrete-time, second-order section,direct-form II filter object
% Plot
hfvt=fvtool(h1,'FrequencyScale','log');
[zd,pd,kd] = bilinear(z,p,k,fs);
_________________________________
and I have noisy Sinusoidal signal and want to
give this noisy signal to filter , for filtering
(remove noise from noisy signal and give me
clean Sinusoidal signal)
how can I do this ?
