Intempo KTB-01 DAB Digital Radio - Grey

This digital revolution also means that you can get more stations broadcast to you within the same radio spectrum that you could with FM, giving you so much more listening choice that you had in the old days. And not only do you get radio as you're used to it DAB transmissions also transmit data which can be displayed on your DAB radio's neat display screen.

Glossary of terms:

DAB - Stands for Digital Audio Broadcasting. Analogue radio is transmitted by placing the audio onto a carrier. If there is any interference or static with the wanted signal then it will be heard on the receiver's speaker. Digital however is transmitted in the form of a digital stream. The decoder in the radio knows what data is needed to re-construct the original signal, so any other unwanted signal is discarded.

Ensemble/Multiplex - Unlike analogue systems, digital radio groups together separate signals from a number of stations and transmits them as a complete, interleaved data stream. This is known as an Ensemble or Multiplex. Up to ten digital services can be transmitted in a single multiplex. This allows several programmes or services to be transmitted on a single frequency.

Service - Radio stations e.g. Radio 1 are known as services when talking about DAB transmissions.

Bit rate - In simple terms when talking about music the higher the bit rate is the better the sound quality will be. For near CD quality audio128Kbps (kilo bits per second) will suffice. So stations that are continually playing music etc use 128Kbps. Stations that generally only transmit speech etc. such as news stations can use 64Kbps as speech doesn't require such a high bit rate.

RDS - Radio data system. The broadcaster can include data with their transmission. This data can then be displayed on the user receiver in a scrolling text format. The Data can include information such as station name and traffic announcements etc.
