I am looking for the autocorrelation function for a specific kind of square wave. I need the autocorrelation function for a square wave with a variable duty cycle and a random phase shift along the period with amplitude -1 to 1. The autocorrelation function for a square wave with .5 duty cycle is a triangle wave varying between 0 and .5, repeating every period. Numerically, I have been able to find the autcorrelation function for a square wave with greater than and less than .5 duty cycles. The functions look similar to a triangle wave, except that they have flat portions instead of peaks on the low part of the graph. Any help or information will be greatly appreciated! Thanks! Sasha D.
