Learning Experience : Convolution and Correlation

This was our first Experiment.In this experiment the output is calculated for 3 cases.we Implemented Correlation (Linear and Circular) and Correlation (auto and cross) using C.The input is taken. In case 2 and case 3 we delayed the input sequence. The basic correlation is the comparison of the 2 discrete time  signals.it.Correlation determines the degree of similarity between 2 signals.Convolution is a mathematical way of combining two signals to form a third signal.When we increase the length of signal effect of aliasing was also observed in this experiment.
