Chapter 11, Problem 16STP

To determine

The conversion of varying electric current produced by CD player in radio station into radio waves.

Explanation of Solution

Introduction:

The production of radio waves in radio stations using CD player comprises of two steps, conversion of sound waves to electric signals and generation of a radio frequency wave from an electric signal.

A CD converts the music into a varying electrical current. The electrical signal or current produced by a CD player is amplified and combined with a radio wave and the process is called modulation. The combined signal is then a radio frequency signal. A modem is used to convert the energy to sound waves.

Conclusion:

Hence, electric current produced by a CD player in radio station is converted into radio waves. .
