Digital tuner

Digital tuner

A digital tuner is a tuning device that allows a television or radio set to receive signals via airwaves, satellite, or cable and translates them into a signal the device can display. A tuner is useful for receiving digital broadcasts over the air or via satellite and displaying it on a high definition television or standard definition television digital television set. Tuners are also used in radio receivers to tune in radio stations digitally (0.2 MHz increments for FM in the US, but less in other countries, thus most FM tuners use 0.1 MHz or 0.05 MHz increments), as opposed to analog dialing. Radio signals can also be received by digital radio tuners, which receive audio signals via satellite. A "digital tuner" could also refer to an ATSC tuner.
