Linear convolution and circular convolution


In the first experiment we performed the Linear convolution and circular convolution.
Linear convolution: Linear convolution shifts linearly. It is operation to calculate the output for any linear time invariant system given its input and its impulse response. we can perform linear convolution from circular convolution, but the thing zero padding must be done upto L+M-1 inputs.
Circular convolution: Circular convolution shifts circularly. It is the same as linear convolution but considering that the support of the signal is periodic. Convolution is done but in circular pattern, depending upon the samples of the signal.
