HAve you tried powerbw ?

Hi,

I understand that you want to find the bandwidth of the signal attached above.

To find the bandwidth of a signal in MATLAB, the 'powerbw' function can be used. 'powerbw(x)' returns the 3-dB (half-power) bandwidth 'bw' of the input signal 'x'. Here is an example:

% Generate a test signal
Fs = 1000; % Sample rate
t = 0:1/Fs:1; % Time vector
f = 10; % Signal frequency
x = sin(2*pi*f*t); % Sinusoidal signal

% Calculate the bandwidth using powerbw
bw = powerbw(x, Fs);

% Display the results
disp(['Bandwidth: ', num2str(bw), ' Hz']);

Bandwidth: 0.15027 Hz

For more information on 'powerbw' function, refer to the below linked documentation:

Hope this helps!
