Response of LTI Systems to Arbitrary Inputs: The Convolution Sum

摘要

The major theme of the paper is the characterization of discrete-time signals and systems in time domain. Here we characterized LTI systems by their unit sample response h(n) and derived the convolutions summation, which is the formula for determining the response y(n) of the system characterized by h(n) to any given input response x(n). We also deal some simple methods to determine the convolution.
