To implement a bandpass filter in MATLAB, you can use the designfilt
function from the Signal Processing Toolbox to design a filter and then use the filter
function to apply the filter to your signal. Here's an example code snippet that demonstrates the process:

In this example, we first define the desired passband and stopband frequencies, as well as the passband ripple and stopband attenuation. We then use the designfilt
function to create a fourth-order IIR bandpass filter with these specifications. We load an example ECG signal and apply the filter using the filter
function, before visualizing the original and filtered signals using the plot
function.
