About DAB (Digital Audio
Broadcasting)
What is DAB system?
DAB (Digital Audio Broadcasting) is one of the digital
radio broadcasting systems available today. It can
deliver digital quality sound without any annoying
interference or signal distortion. Furthermore, it can
carry text and data.
In contrast to FM broadcast, where each program
is transmitted on its own frequency, DAB combines
several programs (called “services”) to form one
“ensemble.”
The “Primary component” (main radio station)
is sometimes accompanied by a “secondary
component” which can contain extra programs or
other information.
