CONVOLUTION


In mathematics (in particular, functional analysis) convolution is a mathematical operation on two functions (f and g) to produce a third function that expresses how the shape of one is modified by the other. The term convolution refers to both the result function and to the process of computing it.This experiment was based on the different types of convolution . 
We had studied about convolution in the last semester in Signals and systems. In convolution we have done linear convolution which is based on linear time invariant system.Circular convolution is defined for finite length functions.We have calculated LC using CC by padding the input sequences with zero. Convolution is quite often used as a method of implementing filters of various types.We have observed the output on Code composer studio (CCS).

  1. Convolution is applicable for non periodic signals as well!

  2. Conolution is the start of signal processing!

  3. In digital signal processing, frequency filtering can be simplified by convolving two functions (data with a filter) in the time domain, which is analogous to multiplying the data with a filter in the frequency domain

  4. circular convolution causes aliasing of signals

  5. LC using CC is obtained when N>=L+M-1
