DSP PROGRAMS IN C & MATLAB 1. Linear Convolution AIM: To verify Linear Convolution. EQUIPMENTS: Operating System – Windows XP Constructor - Simulator Software - CCStudio 3 & MATLAB 7.5 THEORY: Convolution is a formal mathematical operation, just as multiplication, addition, and integration. Addition takes two numbers and produces a third numbe r, while convolution takes two signals and produces a third signa l. Convolution is used in the mathematics of many fields, such as probability and statistics. In linear systems, convolution is used to describe the relationship between three signals of interest: the input signal, the impulse response, and the output signal. In this equation, x1(k), x2(n-k) and y(n) represent the input to and output from the system at time n. Here we could see that one of the input is shifted in time by a value every time it is multiplied with the other input signal. Linear Convolution is quite often used as a method of implementing filters of various types.
