The z-Transform: Introduction

The z-Transform: Introduction. Why z-Transform? Many of signals (such as x(n)=u(n), x(n) = (0.5) n u(-n), x(n) = sin(n ω ) etc. ) do not have a DTFT. Advantages like Fourier transform provided: Solution process reduces to a simple algebraic procedures

Z Transform

Z Transform. The z-transform of a digital signal x[n] is defined as: This transform is said to be unilateral as it does not take into account any values prior to n = 0 .

The Inverse z -Transform

The Inverse z -Transform. The inverse z transformation can be performed by using a few results from complex variable theory. Suppose that we integrate one (1) from z =0 to z= 1:. The integrals become more involved when the path of integration is in the complex plane.
