### Correlation - Digital Signal Processing

Since this signal reversal is the only difference between the two operations, it is possible to represent correlation using the same mathematics as convolution.This requires preflipping one of the two signals being correlated, so that the left-for-right flip inherent in convolution is canceled. For instance, when a[n] and b[n], are convolved to produce c[n], the equation is written: a[n] * b[n ...
