In first Experiment we learned about linear and circular Convolution. Convolution is the mathematical operation on two signals to produce the third signal that expresses how the shape of first signal is modified by the other.The length of the signal in the Linear convolution is N=L+M-1 and the length of the signal in Circular Convolution is Max(L,M). In Circular Convolution we get aliased output.We can solve linear and circular convolution using formula or tabular method. In linear convolution signal may not be periodic but in circular convolution signal is assumed to be periodic . Linear convolution is used in real life applications.
