How to draw a square wave if you have amplitude and period

How to draw square wave and draw a cross corelation if I have amplitude A=3,period T=3 and width of one impuls is teta=3*0.5.

Hi @marko skoric,

We can use the ‘square’ function in MATLAB to generate a square wave. For more details on how to do so, please refer to the documentation of the same below-

We can then plot this generated wave using the ‘plot’ function, more details on the same can found below-

Next, to draw the cross-correlation, I am assuming that you aim to draw the cross-correlation of this square wave with itself. We can compute this using the ‘xcorr’ function in MATLAB. I have attached a code snippet below as a reference on how to do the same.

% Compute the cross-correlation of the square wave with itself 
[crossCorr, lag] = xcorr(squareWave); 

For more details on using the ‘xcorr’ function, please refer the below link-

Finally, we can plot ‘crossCor’ to visualize the results. I have attached screenshots of the of the square wave and its cross-correlation for further reference, below.
