An analog signal is a signaling method that uses continuous changes in the amplitude or frequency of a radio transmission to convey information. The term is often used in comparison with a digital signal. Analog television (and its analog storage mediums) are said to be inferior to today's almost universally used digital television. This assumption is debatable.[1]
