INTRODUCTION TO AMPLITUDE MODULATION

Purpose:

The objectives of this laboratory are:

1. To introduce the spectrum analyzer as used in frequency domain analysis.

2. To identify various types of linear modulated waveforms in time and frequency domain

representations.

3. To implement theoretically functional circuits using the Communications Module Design

System (CMDS).

Equipment List

1. PC with Matlab and Simulink

I. Spectrum Analyzer and Function Generator.

This section deals with looking at the spectrum of simple waves. We first look at the spectrum of

a simple sine wave.

To Start Simulink: Start Matlab then type simulink on the command line. A Simulink Library

Window opens up as shown in figure 1.
