Witryna1 mar 2024 · Hers is the code, that I am using to build my filter: Wn = [Fl (i) Fh (i)] / (Fs/2); [ z, p, k ] = butter ( N, Wn, 'bandpass' ); % [z,p,k] = cheby1 ( N, Rp, Wn, 'bandpass' ); [ sos, g ]=zp2sos ( z, p, k ); f = dfilt.df2sos ( sos, g ); Can anyone help me with designing proper 1/3-Octave-Band filters for that frequency range (0.5÷100)Hz? WitrynaTo test the bandpass filter, designed by the Image Parameter technique, a sinusoidal signal at 2.45 GHz is recovered from the noisy input signal. The noise input signal is generated by the inclusion of zero-mean random noise and a blocker at 2.35 GHz to the input signal. Construct a input and a noisy input signal with 8192 samples.
