Z-transform

Matlab program to find Z-transform, Inverse Z-transform, Zeroes and Poles of given sequence.

Matlab code

clc;

close all; clear all; syms n z;

y=input('Enter the sequence x[n]: '); % Where n is sequence variable

X=ztrans(y);

disp('Z-transform Z[n] of given function');X x=iztrans(X);

disp('Inverse Z-transform of X');x [num den]=numden(X); z=solve(num);

disp('Zeroes of Z[n]');z p=solve(den); disp('Poles of Z[n]');p

Command Window

Enter the sequence x[n]:2^n

Z-transform Z[n] of given function X =

z/(z - 2)

Inverse Z-transform of X x =

2^n

Zeroes of Z[n] z =

0

Poles of Z[n] p =

2
