Question

In each of the problems please solve manually (which is worth 75% of the problem points) and then show some MATLAB verification and include the code (which is worth 25% of the problem points. In other words a problem that is submitted without any MATLAB cannot have a grade larger than B)

Answer 1

We need to remove rad/sample

If we want a unity gain, we can normalize the transfer function

So the MATLAB script for obtaining the frequency response of the designed FIR filter

Case - I: When normalization is not required

clc;
clear all;
close all;

b = [1 1.0717 1];
a = 1;
freqz(b,a);

The frequency response in this case will be

Case II When we have normalized the filter

clc;
clear all;
close all;

b = [0.3256 0.3489 0.3256];
a = 1;
freqz(b,a);

The frequency response will be
