I understand that you are facing an issue while generating a bandpass signal in MATLAB.
To generate a bandpass signal with proper sampling frequency using MATLAB, kindly refer to the following example:
fs = 1000; % sampling frequency in Hz
t = 0:(1/fs):1; % time vector
noise = randn(size(t)); % generating white noise with normal distribution
[b,a] = butter(2, [50/(fs/2), 200/(fs/2)], 'bandpass'); % generating filter coefficients for a 2nd order bandpass filter with a passband between 50Hz and 200Hz
x = filter(b,a, noise); % applying filter to noise signal
For more information regarding the "butter" and "filter" functions, kindly refer to the following documentation:
I hope this answer helps you.
