How Do Digital Radios Work?
Digital Radio Digital radios receive information via digital signals. The digital signals are sent as bundles, or packets, of information combining analog and digital information. Digital signals can be compressed, which allows more information to be sent and received at one time. Digital radio receivers sort through distorted signals and remove static and fading, which allows the audience a cleaner listening experience. A digital radio is required to receive the free digital signals. IBOC Sidebands In-Band On-Channel broadcasting is the choice made by the FCC to transmit digital radio. To make this system work the digital signals are allowed to ride along side analog signals so that radio frequency allocation remains the same. Digital sidebands are added out of the range of the carrier frequency. This is to prevent interference with the existing analog signals. It has been noted that there are still small interference issues despite this arrangement. Both AM and FM stations can use th
