The Computer as an Analysis Tool

This problem illustrates the concept of amplitude modulation. Suppose that the function c(t) is equal to a triangular waveform that has peak values of 1 and −1 and frequency f1. Similarly, m(t) is a square wave function that varies between +1 and −1 and has frequency f2. Write a computer program that plots the amplitude- modulated waveform described by the equation

for the case f1 = 10 Hz, f2 = 1 Hz, and a = 0.4. The factor a is called the modulation index, and hertz (Hz) has the units of cycles per second.
