英语翻译
A new development in FM radio is HD,or High Definition,Radio.HD Radio works,in principle,the same as Digital TV.The digital audio signal of the radio station is broadcast as 1s and 0s along the carrier wave instead of as an RF spray.The radio that receives this signal is a radio with a digital tuner that can catch those signals.HD Radio provides clearer audio to a radio,but it is directional in its reception (directional meaning you have to have your radio in the direct path of the transmission from the tower to receive the signal).HD Radio also provides text information from the studio that includes song title,artist,station ID,weather alerts and other messages sent by the studio to HD Radios.
