autocorrelation characteristics of super gaussian optical pulse with gaussian optical pulse.

Yes, they are the same.

It is the integral over the (perpendicular) autocorrelation function.

Unfortunately, there are also some problems with the use of the autocorrelation. Voiced speech is not exactly periodic, which makes the maximum lower than we would expect from a periodic signal. Generally, a maximum is detected by checking the autocorrelation
