STEREO SOUND SYSTEM

How Car Audio Works
FM reception
Ionosphere
AM and FM radio signals are broad-
cast from transmitter towers located
around your city. They are intercepted
by the radio antenna on your car. This
signal is then received by the radio and
sent to your car speakers.
When a strong radio signal has reached
your vehicle, the precise engineering
of your audio system ensures high
quality reproduction. However, in some
cases the signal coming to your ve-
hicle is not strong and clear. This can
be due to factors such as the distance
from the radio station, closeness of
other strong radio stations or the pres-
ence of buildings, bridges or other
large obstructions in the area.
AM reception
B750A01L
AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequency. These
long, low frequency radio waves can
follow the curvature of the earth rather
than travelling straight out into the
atmosphere. In addition, they curve
around obstructions so that they can
provide better signal coverage.

Buildings

FM broadcasts are transmitted at high
frequency and do not bend to follow

the earth's surface. Because of this,
FM broadcasts generally begin to fade
at short distances from the station.
Also, FM signals are easily affected by
buildings, mountains, or other obstruc-
tions. These can result in certain lis-
tening conditions which might lead you
to believe a problem exists with your
radio. The following conditions are
normal and do not indicate radio trouble:
