Mathematical Operations on Basic Discrete Time Signals with MATLAB Programming

Abstract

This paper deals with the simulation of some of the discrete time signals using MATLAB and discusses some of their mathematical operations and properties. Basic discrete time signals with MATLAB simulation is discussed in introduction along with the time domainand frequency domain analysis of discrete time signals.The frequency domain analysis is discussed with help of two important transform technique i.e. Z-transform and Discrete Fourier transform. It is thus important to learn first how to generate signals in time domain and perform basic operations on them, which are the main objectives of this paper. A secondary objective is to learn the application of some basic MATLAB commands and its usagein solving simple digital signal processing (DSP) problems.
