EXPERIMENT - 15

AIM

To demonstrate Z-transform and it's Inverse in MATLAB.

THEORY

Z Transform of Discrete Signal x(n) is given by

$Z(x[n])= X(z)=\sum^{\infty}_{n=-\infty}x[n]z^{-n}$

where $z=re^{i\theta}$

MATLAB COMMANDS USED

* syms x n;
* ztrans(p);
* iztrans(x)

MATLAB CODE

syms n z ;
ztrans(exp(3*n)/5^n)
iztrans(3*z/(4*z-1))

RESULT

The Z transform Related functions has been demonstrated in MATLAB.
