Convolution and Correlation

The aim of the experiment was to study linear convolution, circular convolution and correlation. In circular convolution, aliasing effect i.e folding of sequence was observed. 

We concluded that in linear convolution, length of output signal N=L+M-1. For circular convolution, length N=max(L,M).

We studied auto-correlation and cross-correlation. For auto-correlation, the observation was that the output signal is a palindrome sequence and the output of correlation is both-sided.

Cross correlation is the correlation between two signals to measure the degree of similarity.
