Question

What is periodic convolution? Explain with example.

Answer 1

it is defined for function or group more than Euclidean space
for e.g. such as discrete time Fourier transform can be defined in a circle and confolved by periodic convolution...

Answer 2

Hey your ans
What is called periodic convolution?
The circular convolution, also known as cyclic convolution, of two aperiodic functions (i.e. Schwartz functions) occurs when one of them is convolved in the normal way with a periodic summation of the other function. That situation arises in the convolution.
