Abstract
Fourier and Laplace transform were proposed only for analyzing the continuous signal in frequency domain. But there was no transformation tool for analyzing signals in discrete time domain whereas there were necessity to analyze the discrete signals and their responses with different input signals. To meet the requirement, the Z-transform was introduced by the famous scientists Ragazzini and Zadeh in the sampled data control group at Columbia University in 1952 [1].
