Hi everyone,

I'm trying to filter an ECG signal but I am unsure how to filter the data and then plot the filter with my own data using the parameters set. I know that fvtool and freqz can plot the magnitude and phase but I can't figure out how to plot the filter on my data (yes I've tried using plot! π ) I've used a ton of different filtering techniques and my latest can be seen below (taken from a previous post). Can I use "plot" to plot my data with this filter and if so how? Please let me know as I am desperate!!! Thank you in advance.

` Fs = 2000; % Sampling Frequency`

Fn = Fs/2; % Nyquist Frequency

Wp = [2 100]/Fn; % Filter Passband (Normalised)

Ws = Wp .* [0.5 1.2]; % Filter Stopband (Normalised)

Rp= 1; Rs= 50; [n,Ws] = cheb2ord(Wp,Ws,Rp,Rs); [b,a] = cheby2(n, Rs, Ws); [sos,g] = tf2sos(b,a); %figure(1)

%freqz(sos, 1024, Fs)
