Re: Cross correlation in signal analysis

I'm not very familar with your examples. Basically I was making little
experiment in Matlab. Since I learned about correlation, I tried to
see what I can do with it. So I generated on strictly deterministic
signal sinusoid and other stohastic signal using function randn. Since
these two signals are totaly uncorrelated I would exect that cross
corelation is very small. And in fact it is comparing with
autocorrelation of sinusiod signal. Now, I'd like to find some example
in Matlab, how this can be used to detect sinusoid if it contains
random noise.
Basically, I need Matlab examples I can play with in order to
understand correlation and its use better
