All You Need to Know About Digital Radio
Gone are the days to discuss about AM & FM. Now is the time to welcome a new member into the radio family-Digital Radio, a way to the new future.To analog radio, digital radio is similar to what digital television is to the standard analog television. After the instauration of FM back in the 1970s, debut of digital radio is the most significant upgrade to happen in the world of radio.
Digital radioencodes sound signals into digital signals in order to transmit them. The encoded signals are then decodes at the receiver and what you get in the end is the superb CD-like sound quality.Whilst the quality ofAM/FM is affected due to various interferences caused by walls, buildings and other structures; the digital radio filters out all the interferences and the output is highly clear. The only downside is that either you will get a good quality signal or you will get nothing.Moreover, the digital radios are very easy as the listener just has to enter the station name and the radio will automatically lock on the specified station.
Features of Digital Radio
- Along with the information that can be sent in addition to the sound, the digital radios enable the listeners to view information such as the name of the song playing currently, the station they are on, phone numbers corresponding to the ads, news feeds, album art and what not. Similar to the digital televisions, the digital radios are equipped with on-board storage which allows the listeners to pause and rewind the live radio.
