Question

What is linear and circular convolution

Answer 1

Linear convolution is the basic operation to calculate the output for any linear time invariant system given its input and its impulse response. Circular convolution is the same thing but considering that the support of the signal is periodic

Answer 2

Linear convolution is the basic operation to calculate the output for any linear time invariant system given its input and its impulse response.

The circular convolution, also known as cyclic convolution, of two aperiodic functions occurs when one of them is convolved in the normal way with a periodic summation of the other function
