What is HD radio?
HD Radio is a type of digital radio technology that offers significantly higher audio quality than traditional AM or FM radio.
HD Radio stations are broadcast using a digital signal that is compatible with existing radio receivers.
However, to avoid bad sound quality and to take advantage of the improved sound quality, you’ll need an HD Radio receiver.
HD Radio technology was developed by iBiquity Digital, a privately held company based in Columbia, Maryland.
About HD Radio Signal:
Those radio waves which carry analog AM and FM signals can transmit a limited amount of information.
This is because of the nature of these waves and the station spacing they use on frequency bands.
For the separation of FM stations, 200 kHz frequency is used but AM stations are separated with only 10 kHz.
Also, FM stations allow broadcasting higher quality audio in stereo because of large spacing.
Although FM signals can transmit a healthy amount of information for higher-quality signals, but it uses too much bandwidth.
So, to solve the bandwidth issue HD radio uses the compression of digital signals.
By doing so more information can be sent using less radio bandwidth.
How does HD radio work?
HD Radio is a digital broadcasting standard that delivers CD-quality audio with less interference and static.
It does this by splitting the radio frequency spectrum into hundreds of digital channels, which are then transmitted to receivers as data packets.
These packets can be reassembled into a clear, single audio stream by the receiver.

HD Radio also includes an Emergency Alert System (EAS) that can interrupt regular programming to deliver important emergency information, such as severe weather alerts or Amber Alerts.
HD Radio signals are currently broadcast by more than 2,000 radio stations across the United States.

You get more information
HD Radio receivers are able to provide more information than traditional analog radios. This is because of the benefit of HD radio know as “updating real-time information”.
You can get to know about the song that’s playing, such as the artist name, song title, and album art.
They can also help you identify songs you hear on the radio but don’t know the name of. On the other hand on analog radios you can only listen the track but can not know about the details.
