True or False: There can be more than 3dB between any two adjacent analog video channels.

The statement is false because in traditional analog video systems, particularly those utilizing coaxial cable, the standard practice is to maintain a maximum difference of 3 dB between adjacent channels to ensure minimal interference and proper signal quality. This principle helps to avoid distortion and ensures that each channel can be clearly differentiated from its neighbors.

In cases where the signal level difference exceeds 3 dB, one channel could cause interference or signal degradation to another, resulting in reduced picture quality, ghosting, or other issues with the transmitted signals. This principle is fundamental to maintaining the integrity of analog broadcasts, where the clarity and quality of video signals are crucial.

Furthermore, while digital channels may have different considerations regarding signal strength and interference, the question specifically centers on analog video channels. Thus, the established guideline holds true across various systems that transmit analog video. Therefore, exceeding the 3 dB threshold between adjacent analog channels is not typical practice and is generally avoided.
