ABSTRACT

Mathematically, signals are represented as a function of one or more independent variables. At this point, we are focusing the attention on signals that involve a single independent variable. Conventionally, it will generally refer to the independent variable as time. There are two types of signals: continuous-time signals and discrete-time signals. In this chapter will focus on the kinds of signals

This chapter gives you a quick way to become familiar with the MATLAB software by introducing you the basic features, commands, and functions. You will discover that entering and solving complex numbers in MATLAB is as easy as entering and solving real numbers, especially with the help of MATLAB built-in complex functions. Upon completion this chapter ,and Appendix A you should know how to start MATLAB , how to get HELP , how to assign variables in MATLAB and to perform the typical complex numbers operations (i.e., complex conjugate , addition , subtraction , multiplication , division , expression simplification) and the conversions of complex numbers in both rectangular and polar forms with and without using MATLAB built-in functions .
