what is analog television

Analog television service is the traditional method of transmitting television signals. Analog transmission has been the standard broadcast technology since the inception of television. Analog is not as efficient as digital television: it uses up much more of the valuable spectrum than digital, and TV stations can only transmit one channel of programming with an analog signal versus up to four or more programs with a digital signal in the same amount of spectrum. Analog is also susceptible to interference and “snow” that make a picture less clear.
