Sampling and Reconstruction - Ptolemy Project
Chapter 11 Sampling and Reconstruction Digital hardware, including computers, take actions in discrete steps. So they can deal with discrete-time signals, but they cannot directly handle the continuous-time signals that are prevalent in the physical world. This chapter is about the interface between these two worlds, one continuous, the other ...

The signal correlation operation can be performed either with one signal (autocorrelation) or between two different signals (crosscorrelation).
