Final answer:
Multiplexing allows multiple users to share the same channel frequency and transmit simultaneously, crucial for TV broadcasting on VHF (54-88 MHz and 174-222 MHz) and UHF (470-1000 MHz) spectrum.
Step-by-step explanation:
Multiplexing is the process that allows users to share the same channel frequency, where multiple users can transmit simultaneously. This is essential in the context of television broadcasting, where channels such as those on very high frequency (VHF) and ultra-high frequency (UHF) spectrums are used to carry a large amount of visual and audio information. VHF TV channels utilize frequencies in the range of 54 to 88 MHz and 174 to 222 MHz; whereas UHF TV channels operate in a higher frequency range of 470 to 1000 MHz. Television broadcasts are a form of electromagnetic waves, and the specific ranges of frequencies they utilize are designed to accommodate the bandwidth necessary for transmitting a high-quality signal. This enables viewers to receive clear audio and visual content through their television sets. Multiplexing techniques are crucial in efficiently managing these frequencies and in providing reliable service to a large number of users simultaneously.
