How Does HD Radio Broadcasting Work?
(Let’s Find Out)
To be honest with you, radio hasn’t really changed for the past 80 years except the fact that people have added more channels and are now trying to get you for your money. The last biggest thing that happened was back in the 1960’s and 70’s, it was the widespread adoption of Frequency Modulation.
When people hear of HD radio, the assume that it is like HDTV, but the HD in TV is totally different that the HD in radio, because the HD in TV stands for high definition, and they think the HD in radio means high definition radio. On the the other hand, it does seem that HD Radio has high qualification. One of it's many great features is that ot can multicast multiple channels on just 1 frequency. One more great feature that I personally like is that if an HD Radio receiver loses the digital signal, it seamlessly fades back to analog FM until the digital signal returns.
