calculating on time of signal

i have 2 square signal with the same amplitude=5 but 2 different on time the first one stays on for 0.4 seconds and the other one for 0.6 and i need a block or a code to use in matlab function that can calculate the time and if it is =0.4 a bit 0 will be the output and if on time was 0.6 bit 1 will be the output.

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.
