The term NTSC stands for National Television System Committee, which refers to the analog color television system that was widely used in North America and parts of South America before the transition to digital broadcasting. The NTSC standard was established to provide a method for broadcasting color television signals that would remain compatible with existing black-and-white televisions.

In this context, the correct answer being an analog fast scan color TV signal reflects the significant characteristics of NTSC. It transmits video at a rate that allows for rapid scanning of the television image, providing the viewer with a real-time experience of watching broadcast television. The use of specific frequencies and modulation techniques in this system enables the transmission of color information in a manner that can be correctly interpreted by compatible receivers.

The other options relate to different transmission types or technologies that do not pertain to NTSC. For instance, a digital video signal involves a different encoding system, and satellite transmission methods address the delivery of signals via satellite technology rather than over terrestrial broadcasting. Likewise, a frequency-modulated audio signal specifically pertains to audio transmissions, rather than the video transmission characteristics of NTSC.
