Analog television is a technology that transmits television signals using continuous waves. It encodes video and audio information into electrical signals, which are then broadcast over the airwaves. Viewers need a television set equipped with an analog tuner to receive these signals, allowing them to watch programs. This system was widely used until the transition to digital television began in the early 2000s. Analog signals are more susceptible to interference and degradation, leading to poorer picture quality compared to digital signals. As a result, many countries have phased out analog broadcasts in favor of digital technology.
