# How to Implement Convolution

Learn how to implement convolution in digital systems.

## We'll cover the following

If an input signal $x[n]$ is applied to a discrete-time system with the impulse response $h[n]$, the output $y[n]$ is given by convolution that is implemented through the following expression:

$y[n] = x[n]*h[n] = \sum_m x[m]h[n-m]$
