Magnetic shields in “upconverter” prevent undesired signals.
Magnetic Shield Corp. shields are employed in the transmission installation process at the broadcasting stations.
The output of the exciter must meet a stringent mask for the signal mandated by the FCC, that manages in band and out of band FM spurious emissions.
The RFU (upconverter) uses Magnetic Shield shields to complete the conversion without adding undesired signals that would violate the FCC requirements.
As demand and technology expand, audio clarity previously afforded only by the audiophile will be as close as your radio.
1. Stations bundle analog and digital audio signals (with textual data, such as artist and song information, weather and traffic,
and more).
2. The digital signal layer is compressed using iBiquity’s HDC compression technology.
3. The combined analog and digital signals are transmitted.
4. The most common form of interference, multipath distortion, occurs when part of a signal bounces off an object and arrives at the receiver at a different time than the main signal.
HD Radio receivers are designed to sort through the reflected signals and reduce static, hiss, pops and fades.
5. The signal will be compatible with HD Radio receivers and analog radios.
