Final answer:
The electronic signal that transmits image information from a television camera to a monitor is known as the video signal. It utilizes various frequency bands within the electromagnetic spectrum, such as VHF and UHF, and is transmitted in an AM format for video, while audio is transmitted using FM.
Step-by-step explanation:
The electronic signal which carries image information from a television camera to a viewing monitor is termed the video signal. Television broadcasts work within the electromagnetic spectrum and use both VHF (Very High Frequencies) and UHF (Ultra High Frequencies) to transmit audio and visual data. Channels in the VHF range use frequencies between 54 to 88 MHz and 174 to 222 MHz, whereas the UHF band utilizes frequencies from 470 to 1000 MHz.
For a clearer transmission, audio and video data are often digitized, converting the signal into a series of binary ones and zeros, employing computer algorithms to enable data compression. This allows for a more robust transmission, particularly when signals are weak.
The television video signal is particularly transmitted as AM (Amplitude Modulation), unlike the audio which uses FM (Frequency Modulation). Received by antennas, these signals are then processed to display the television content that viewers watch on their screens, including on modern LCD televisions where millions of pixels create the image.
