What is Digital Radio
What is Digital Radio?
DAB (Digital Audio Broadcasting) is the next generation of radio. DAB was developed 
in Europe by a consortium of broadcasters and manufacturers.
DAB uses digital compression techniques to transform the source material, i.e. music 
and speech, into digital computer code before it is transmitted. The computer code 
consists of electronic ‘ones and zeros’ called binary digits or bits. The binary code is 
then multiplexed or grouped together to create a superior signal, when compared 
with the older analogue system, with the following key benefits:
• Near CD quality sound.
Because DAB is binary coded, the receiving equipment is only expecting to receive a 
series of ones and zeros, so any other interference is ignored, resulting in very high 
quality audio.
• Interference free reception.
Analogue systems suffer from an effect called ‘multipath distortion’. This is caused 
because radio waves do not behave in an orderly fashion, but bounce and reflect off 
buildings and mountains etc. DAB sees this as an advantage and uses the direct and 
reflected signals to actually reinforce the end result.
• No need to re-tune.
A single DAB frequency can be used to cover the whole of the UK, so solving many 
of the problems experienced with the earlier analogue system.
• Scolling text
Broadcasters can transmit text to your radio. This way you can read the name of the 
DJ, artist, song title or any other information that is broadcast.
• DAB coverage
