How much bandwidth does an analog TV picture require?

An analog TV picture requires 6 megahertz of bandwidth. This is a standard measurement that describes the frequency range necessary for transmitting the various components of an analog television signal, including the picture, sound, and any additional data such as closed captioning. The 6 megahertz bandwidth is essential for maintaining the quality of the video and audio transmission, facilitating the necessary detail and clarity for standard analog television broadcasting.

This specific allocation of bandwidth reflects regulatory standards established for TV broadcasts, ensuring that each channel operates within its designated frequency range without interference from adjacent channels. This bandwidth also accommodates the modulation techniques used to encode the picture and sound information for transmission over the airwaves.
