Noise component as below coded
% Sampling
fs = 22.25;
Ts = 1/fs;
% Time vector
t = 1:Ts:10-Ts;
% Signal
f = 1; % Frequency [Hz]
a = 1; % Amplitude
signal = sin(2*pi.*t.*f); % Sample sinusoidal signal. Your ECG signal goes here.
% Noise
fNoise = 50; % Frequency [Hz]
aNoise = 0.25; % Amplitude
noise = aNoise*sin(2*pi.*t.*fNoise);
noisy_ecg = noise+ecg

Expert Answer
To filter noise from a noisy ECG signal using an autoregressive (AR) filter in MATLAB, you can use the filter function. An AR filter is a type of line
