Concept of Z-Transform and Inverse Z-Transform

X(Z)|z=ejω=F. T[x(n)].

What is the Z-transform with example?

Definition of Z-Transform

In mathematics and signal processing, the Z-transform converts a discrete-time signal, which is a sequence of real or complex numbers, into a complex frequency-domain representation. Also, it can be considered as a discrete-time equivalent of the Laplace transform.

What is the Z-transform of the signal x n )= 3 2 n )- 4 3 n u n?

What is the z-transform of the signal x(n)=[3(2ⁿ)-4(3ⁿ)]u(n)? => X(z)=\frac31-2z^-1-\frac41-3z^-1.

What are the limitations of Z-transform?

Limitations – The primary limitation of the Z-transform is that using Z-transform, the frequency domain response cannot be obtained and cannot be plotted.
