A general purpose correlator
Abstract
A correlator for general laboratory use is described that calculates the time-delayed correlation of two electrical signals in real time. The instrument described is an improved version of a type used for some time. It computes both the correlation and covariance of input signals as a function of time delay and provides an output for displaying the function on an oscillocope or a chart recorder.
