How HD Radio works
HD Radio produces a smooth, natural response and room-fi lling sound that
belies its compact size. HD Radio stations can broadcast data (artist and song
information, weather, traffi c, and more) and multiple channels at their same,
familiar position on the radio dial.
1. The digital signal is compressed using HD Radio compression
technology.
2. Stations bundle both analog and digital audio signals, and the
combined analog and digital signals are transmitted. The signal will be
compatible with both HD Radio receivers and analog radios.
HD Radio receivers are designed to reduce static, hiss, pops, and fades by sorting
through refl ected signals and multi-path distortion. Multi-path distorition is the
most common form of interference, and occurs when part of a signal bounces
off an object and arrives at the receiver at a different time than the main signal.
