In spite of the fact that a survey showed that 66 percent of Norwegians oppose the move while only 17 percent favor it, the Norwegian parliament has given the go-ahead to switch off the FM radio network in favor of digital audio broadcasting (DAB).
|The parliament is swayed by the fact that DAB allows more channels. However, there are two million cars in Norway that do not have DAB receivers. The cost for a good adapter for the FM radio is about $235 Canadian. Many home radios will also be unable to receive the signal although digital TVs will. Critics claim that the move is just too early. Norwegians are not prepared for it and will resent the extra expense and inconvenience it will cause them.|
In digital broadcasting systems, the analog audio signal is digitized, 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 datacasting services, and to decrease the transmission power or the number of transmitters required to cover a region. However, analog radio (AM and FM) is still more popular and listening to radio over IP (Internet Protocol) is growing in popularity.
