Hello Ali,
To achieve this in MATLAB, you can create a function that analyzes the square wave signal to determine its on-time duration and then outputs the corresponding bit value based on the duration.
Refer to the following sample code, this method assumes the square signal starts with an "on" state:
onStateDuration = find(sqaureWave==0,1)-1; %no of on state samples.
inSeconds = onStateDuration/samplingRate; %convert on state duration in to seconds.
if (inSeconds == 0.4)
bitOutput = 0;
else
bitOutput = 1;
end
Make changes to the code for desired behavior.
Regards.
