10 Essay - 10 points
Describe the difference between FM and AM.
Feedback: Amplitude modulation or AM was the first type of modulation developed, early in the 20th
century. When the amplitude or height of the carrier is changed in time with the audio signal, the result is
AM. For FM, instead of modulating the amplitude of the carrier, one can use the audio signal to change the
frequency of the carrier, and that is frequency modulation. The frequency increases and decreases, but the
amplitude of the modulated signal stays constant. The same intelligence has been transmitted. In the
frequencies used in the AM broadcast band, signals can bounce off the ionosphere, especially at night, and
be reflected back to earth at considerable distances from the transmitter. Signals at the much higher
frequencies used for FM generally do not bounce off the ionosphere, and so FM reception is limited to more
or less a line-of-sight path.
11 Of AM and FM, which is the type of transmission that is limited to line-of-sight?
12 What are the three classes of "Clear Channel" stations?
13 What is the current state of satellite radio?
14 What are the geographical limits of Internet radio?
15 What are some of the advantages of DAB (Digital Audio Broadcasting)?
16 What is one of the most important requirements to become a radio broadcasting engineer?
17 What does a Proof of Performance involve?
18 What is the system used for communicating with the public during an emergency currently
known as?

20 Of AM and FM, which is the type of transmission that is limited to line-of-sight?
(A) AM
(B) FM
(C) FM on cable radio systems
(D) AM radio on satellites
21 What is one of the main advantages of FM signals?
(A) Signal travels further using ground waves
