Digital radio is the use of digital technology to transmit and/or receive across the radio spectrum. They may refer to digital transmission by radio waves, including digital broadcasting and especially to digital radio services. They term is also applied to radio equipment using digital signal processing of analog radio signals. In digital broadcasting systems the analog audio signal is digitised, compressed using formats such as MP2 and transmitted using a digital modulation scheme. The aim is to increase the number of radio programs in a given spectrum, to improve the audio quality, to eliminate fading problems in mobile environments, to allow additional data casting services and to decrease the transmission power or the number of transmitters required to cover a region.
