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.

Correlation has so many applications in the area of light transmissions. Laser light pulses length can be measured using correlation.
ReplyDeleteYes. Basically correlation is used to check the similarity between signals.
DeleteCorrelation between input and delayed input gives the same result as autocorrelation, but with a zeroes(equal to the delay). You must have written it in your conclusion. Just thought to add it here too
