Chapter 11, Problem 32R

To determine

To Explain: Which of the following is modified in an AM radio wave A) Speed, B) Frequency, C) Amplitude, D) Wavelength.

Answer to Problem 32R

The correct option is C) Amplitude.

Explanation of Solution

Introduction:

Amplitude modulation is a technique of modulation used in electronic communication, most commonly for transmitting information through a radio carrier wave. The amplitude of the carrier wave is varied in amplitude modulation, in proportion to that of the transmitted message signal.

Amplitude is modified in amplitude modulation radio wave. In amplitude modulation, the amplitude of the carrier wave is varied in proportion to that of the message signal being transmitted.

Conclusion:

Hence, the correct option is C) Amplitude.
