Final answer:
VHF in VHF Radiotelephone stands for Very High Frequency, which is used for television broadcasting within 54 to 88 MHz and 174 to 222 MHz frequency ranges.
Step-by-step explanation:
VHF stands for Very High Frequency. These frequencies are utilized for a variety of broadcasting applications, including television and radiotelephony. Specifically, VHF TV channels occupy two frequency ranges, from 54 to 88 MHz and from 174 to 222 MHz. Comparatively, the FM radio band falls within these VHF channel ranges, specifically between 88 MHz and 174 MHz. Television signals require a broadband to transmit substantial visual and audio information compared to standard radio transmission.
Furthermore, there's also the Ultra High Frequency (UHF) band for television channels. The UHF band covers an even more extensive frequency range from 470 to 1000 MHz. Both VHF and UHF represent significant segments of the electromagnetic spectrum used for over-the-air broadcasting with a traditional roof antenna setup. It is worth noting that the television video signal uses Amplitude Modulation (AM), while audio is carried over Frequency Modulation (FM). Today, satellite and cable transmissions can occur at higher frequencies, and technology is rapidly advancing with the introduction of high-definition (HD) formats.
