Reading in of signals
Signals are read in via the following connection:
^
Direct lines
Direct lines
The following signals are read in via a direct line:
-
Wake-up
-
Digital Audio Broadcasting (Digital Radio) (DAB) L-band signals from the multifunction antenna (A28/11) (via coaxial line)
-
DAB band III signals via the rear window antenna structure and the coaxial line at the antenna rear window FM antenna amplifier (A2/19)
The DAB L-band signals mostly come from conurbation stations. The DAB L-band III signals mostly come from inter-regional stations.
Decoding of signals
The Digital Audio Broadcasting control unit decodes the DAB L-band signals and DAB L-band III signals to obtain PCM (Pulse Code Modulation)
signals.
Transmitting signals
The Digital Audio Broadcasting control unit transmits signals via the following connection:
^
Media Oriented System Transport (MOST)
