Audio - Digital Radio

Digital radio offers much better quality sound than analog radio, and are more resistant to noise and interference. Digital radio works by converting sound into digital code, transmitting the code as a digital signal, and digital radio receivers are able to decode and filter all but the digital signals for static-free sound on the receiving end. Digital radios are also easier to use since they allow menu-based operation and support the Radio Data System (RDS), allowing digital radios to display current program information such as song titles and artists. Additional such as program type (news, rock music, etc.), station IDs, time, or even traffic and travel information for automotive systems that support Traffic Message Channel (TMC).
