Z-transform
text:
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 valued frequency-domain representation. It can be considered a discrete-time equivalent of the Laplace transform. This similarity is explored in the theory of time-scale calculus. While the continuous-time Fourier transform is evaluated on the s-domain's vertical axis, the discrete-time Fourier transform is evaluated along the z-domain's unit circl
