an innovative and universal
broadcast system.
General information ■ DAB stations are indicated by the programme name instead of the
broadcasting frequency.
■ With DAB, several radio programmes (services) can be
broadcasted on a single frequency
(ensemble).
■ Besides high-quality digital audio services, DAB is also able to
transmit programme-associated
data and a multitude of other data
services including travel and traffic
information.■ As long as a given DAB receiver can pick up the signal sent out by a
broadcasting station (even if the signal is very weak), sound
reproduction is ensured.
■ There is no fading (weakening of the sound) that is typical of AM or
FM reception. The DAB signal is
reproduced at a constant volume.
■ Interference caused by stations that are on nearby frequencies (a
phenomenon that is typical of AM
and FM reception) does not occur
with DAB.

picked up by the receiver, the
system switches over to the same
programme on another DAB or FM
station.
