Signal Processing Toolbox™ provides a family of correlation and convolution functions that let you detect signal similarities. Determine periodicity, find a signal of interest hidden in a long data record, and measure delays between signals to synchronize them. Compute the response of a linear time-invariant (LTI) system to an input signal, perform polynomial multiplication, and carry out circular convolution.
|cconv||Modulo-N circular convolution|
|conv||Convolution and polynomial multiplication|
|corrmtx||Data matrix for autocorrelation matrix estimation|
|deconv||Deconvolution and polynomial division|
