RADIO GENERAL INFORMATION

Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help

you understand and save you concern about these “ap-
parent” malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.

Two Types of Signals
There are two basic types of radio signals:

1. AM or Amplitude Modulation, in which the transmit-
ted sound causes the amplitude, or height, of the radio
waves to vary.

2. FM or Frequency Modulation, in which the frequency
of the wave is varied to carry the sound.

Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
