I want to know how one might calculate the cross correlation of two signals by hand. I know that there are a myriad of software applications that will do this for me but I want to understand how it is done by hand. I'm using the expression:(adsbygoogle = window.adsbygoogle || []).push({});

ccxy[k] = ∑ x[n]. y[n+k]

I'm just not too sure what the k is this expression represents.

Thanks in advance!
