Q.8 Correlator

In general, correlation describes the mutual relationship which exists between two or more

things. The same definition holds good even in the case of signals. That is, correlation

between signals indicates the measure up to which the given signal resembles

another signal.

In other words, if we want to know how much similarity exists between the signals 1 and 2,

then we need to find out the correlation of Signal 1 with respect to Signal 2 or vice versa.
