WebNov 30, 2013 · Cross correlation • In signal processing, cross-correlation is a measure of similarity of two waveforms as a function of a time-lag applied to one of them. This is also known as a sliding dot product or … WebSep 25, 2000 · Correlations are the main theme that links together the present chapter. We first motivate the concept of correlation by considering how to compare an input signal to a reference signal. We find that the best signal detector is the correlator. Next we compare correlation with convolution and discover that the …
WebCorrelation is a mathematical operation that is very similar to convolution. Just as with convolution, correlation uses two signals to produce a third signal. This third signal is called the cross-correlation of the two input … WebFigure 6-1 defines two important terms used in DSP.
