The "core spectrum" for digital television channels ranges from?

The "core spectrum" for digital television channels encompasses the frequencies essential for broadcasting digital television signals, typically designated from Channel 2 to Channel 51. This range includes both VHF (Very High Frequency) channels and UHF (Ultra High Frequency) channels, with Channel 2 starting at 54 MHz and Channel 51 ending at approximately 698 MHz. The range is primarily relevant for ensuring that digital signals are transmitted effectively across the television band, allowing for a diverse selection of programming and enhanced picture and sound quality.

Channels above 51 are mostly used for other applications, such as telecommunications and wireless communications, while channels below 2 are generally not used for TV purposes. This delineation helps to avoid interference between different types of broadcast transmissions and clarifies the boundaries of the spectrum specifically reserved for television broadcasting.
