In what is being touted as the biggest technological advance in the radio industry since the FM band made its debut, stations around the U.S. are preparing to begin broadcasting digital signals in addition to their standard analog transmissions. The new technology will allow radio stations to broadcast CD-quality sound, include text with the music, and even to broadcast more than one program on the same frequency. Consumers will need a digital receiver to pick up the new transmissions, and currently, only one station (in Cedar Rapids, Iowa,) has begun digital broadcasting, but industry observers are expecting digital to become the new standard within the next decade.
