It is known that an LTI system is defined by its Impulse Response and the Convolution Operator.

Could some put some intuition behind?

Thank You.

I think this post gives a lot of intuition about Convolution:


In the Signal Processing world, an LTI (Linear and Time Invariant) system basically scales and sums delayed versions of the input signal.

This can be mathematically described using the integral known as convolution.
