what is digital radio

Digital radio is the transmission and reception of sound that has been processed using technology comparable to that used in compact disc (CD) players. In short, a digital radio transmitter processes sounds into patterns of numbers, or “digits”– hence the term “digital radio.” In contrast, traditional analog radios process sounds into patterns of electrical signals that resemble sound waves.

* FM digital radio is capable of providing clear sound comparable in quality to CDs. Digital receivers provide significantly clearer sound than conventional analog radios, just as CDs sound clearer than record albums.

* AM digital radio is capable of providing sound quality equivalent to that of standard analog FM, and sounds dramatically better than analog AM. Some broadcasters believe that digital broadcasting may bring music back to the AM band.

* Digital radio reception is more resistant to interference, and eliminates many imperfections of analog radio transmission and reception. There may be some interference to digital radio signals in areas that are distant from a station’s transmitter.
