The goal of this lab is to learn how to implement FIR filters
in MATLAB, and then study the response of FIR
filters to various signals, including images and speech.
As a result, you should learn how filters can create
interesting effects such as blurring and echoes. In addition,
we will use FIR filters to study the convolution
operation and properties such as linearity and time-invariance.
This mini project concentrates on the use of dconvdemo a GUI for discrete-time convolution.
This demo is exactly the same as the MATLAB functions conv() and firfilt() used to
implement FIR filters.
This demo illustrates an important point about the behavior of a linear, time-invariant (LTI) system. It also
provide a convenient way to visualize the output of a LTI system.
