our first practical of semester six was convolution and correlation.The program for this practical was given in C language. I have substituted the values of x(n) and h(n) in program .Final output length of y(n) for linear convolution is equal to L+M-1. For circular convolution it is maximum value from L(length of x(n)) and M(length of h(n)).Circular convolution gives aliased output.
Auto correlation of signal is even signal and cross-correlation of input signal with delayed signal is same as advanced auto correlated input signal.Correlation was used to test the degree of similarity between two signals.

convolution is used to find op of the filter while correlation is used to find similarity between 2 signals
ReplyDeleteZero padding increases resolution as length of signal increases
ReplyDeleteGiven content is useful for performing convolution and correlation.

ReplyDeleteAliasing means overlapping of the last M-1 values on the first M-1 values of the output
