MATLAB CODE TO FIND OUT THE FREQUENCY AND PHASE RESPONSE

CODE:

clc;
clear all;
a=input('Enter the values for numerator : ');
b=input('Enter the values for denomator : ');
t = tf(a,b,0.1) %give transfer function in Z domain

freqz(a,b); % give freq as well as phase response

OUTPUT:

Enter the values for numerator : [1 2 3]
Enter the values for denomator : [4 5 6]
 Transfer function:
 z^2 + 2 z + 3
---------------
4 z^2 + 5 z + 6
 Sampling time: 0.1
