16. Plotting Amplitude Modulated Waves Step 1: Understanding the problem Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In amplitude modulation, the amplitude (signal strength) of the carrier wave is varied in proportion to the waveform being transmitted. That waveform may, for instance, correspond to the sounds to be reproduced by a loudspeaker, or the light intensity of television pixels. The amplitude modulated signal i defined as: AM-(1 +mxcos(2nfmt)x Acos(2nfet) Where the low frequency (in the range of 1 KHz 2KHz) intelligence signal is M = A cos(2xf1) the high frequency (in the range of 100 KHz-200KHz) carrier signal is and m is the modulating index. If m1, the modulated signal is called over modulated. Step2: First write a comment line (followed by % and three spaces): MATLAB codes for Problem 16 Step 3: Write MATLAB codes to plot three separate figures, where each figure presents the intelligence signal, the carrier signal and the modulated signal in the range 0 to 1 from top to bottom of the figure for the cases with m1, m-1, and ms1. Use figure0 and subplot0 functions. Write MATLAB codes to show xlabel, ylabel, and title in the plots. Consider the amplitude of the carricr/intelligence signal, A-1 V Choose a value from the range 10' to 2 10' for the intelligence frequency fa, a value from the range 100*10' to 200x10 for the carrier frequency f
