WebPlot the sample and theoretical cross-correlation sequences. Create an white noise sequence. Set the random number generator to the default settings for reproducible results. Create two moving average filters. One filter has impulse response . The other filter has impulse response . In signal processing, cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other. This is also known as a sliding dot product or sliding inner-product. It is commonly used for searching a long signal for a shorter, known feature. It has applications in pattern … See more For continuous functions $${\displaystyle f}$$ and $${\displaystyle g}$$, the cross-correlation is defined as: If $${\displaystyle f}$$ and $${\displaystyle g}$$ are both continuous periodic functions of period See more In time series analysis and statistics, the cross-correlation of a pair of random process is the correlation between values of the processes at different times, as a function of the two … See more Caution must be applied when using cross correlation for nonlinear systems.
