Digital Filters
A digital filter uses computation to implement the filtering action that is to be performed on a continuous time signal.

Discrete Time Fourier Series (DTFS)
In continuous-time Fourier series, periodic signals are represented as sum of complex exponentials. The continuous-time Fourier representation of periodic signal

The discrete-time counterpart of Laplace transform is z-transform. The frequency domain analysis of discrete time system allows us to represent

In Fourier transform, one problem we faced that Fourier transform is not applicable for signals that are not absolutely integrable.
