In this experiment ,I used mathematical tools for linear convolution , circular convolution and linear convolution using circular convolution functions and the obtained results were verified with the results obtained from mathematical formulation.In linear convolution if both the signals are causal then the output result is also causal,circular convolution gives aliased output.
Correlattion is mathematical tool used to find similarity between two signal and the output signal is in the form of pallindrome,Hence when signals are same this can be used to find erroe in a signal .
Correlation is used to compare two signals while convolution is used to get output of filter.
ReplyDeleteIf both x[n] and h[n] are causal then the resultant y[n] is also causal.
ReplyDeleteAuto Correlation is used for finding error in the signal.
