Kshitij Singh x is the signal that you want to filter.
How use filter from filter designer?
I created a bandpass filter in Filter Designer by generating the matlab code and stored the filter. Now, how do I actually use it to process my signal. Below is the code generated. Thanks % All frequency values are in Hz. Fs = 5000; % Sampling Frequency Fstop1 = 2; % First Stopband Frequency Fpass1 = 5; % First Passband Frequency Fpass2 = 1000; % Second Passband Frequency Fstop2 = 1200; % Second Stopband Frequency Astop1 = 30; % First Stopband Attenuation (dB) Apass = 1; % Passband Ripple (dB) Astop2 = 30; % Second Stopband Attenuation (dB) match = 'passband'; % Band to match exactly % Construct an FDESIGN object and call its BUTTER method. h = fdesign.bandpass(Fstop1, Fpass1, Fpass2, Fstop2, Astop1, Apass, ... Astop2, Fs); Hd = design(h, 'butter', 'MatchExactly', match);
