Hi, Can anybody help me plot a combined frequency response of 2 filters in Hz? Hk=Hk1.*Hk2; The sampling freq for Hk1 is 96Khz and the sampling freq for Hk2 is 24Khz. figure(1) plot(96e3*w/(2*pi),20*log10(abs(Hk2)),'y'); hold on figure(1) plot(24e3*w/(2*pi),20*log10(abs(Hk3)),'b'); hold on I use above lines to plot the filters separately and they look right. To plot a combined filter Hk, what sampling rate should I used? figure(1) plot("????"*w/(2*pi),20*log10(abs(Hk3)),'b'); Thanks, EngGan |
