Convolution and Correlation

                 In this experiment, we performed linear convolution, circular convolution, linear by circular convolution and auto and cross correlation. We used C code for programming all the cases.For N<L+M-1 the convoluted output signal has signal value overlap. This is known as aliasing effect. 

               Correlation is used to find out similarity between signals.The output signal due to auto-correlation was found to symmetric.
