Saab 9-5 Audio System
Shadow effect
Because FM radio waves travel in straight
lines from the transmitter, a shadow effect
can occur when tall buildings or hills
obstruct the propagation path from the
transmitter to the car.
Sources of FM interference
Interference to FM reception can be caused
by the electrical systems in other vehicles,
particularly if the signal from the transmitter
is weak.
Cross-modulation
When the radio is tuned to a weak transmit-
ter in the vicinity of a stronger one, the car’s
antennas will receive signals from both.
Such interference is apparent when the
unwanted broadcast can be heard faintly in
the background.
