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 receive these signals through antennas, allowing them to watch programs on their TV sets. This system was widely used before the transition to digital television, which offers better picture and sound quality. Analog signals can be affected by interference, leading to issues like static or ghosting on the screen. The switch to digital broadcasting began in the early 2000s, making analog television largely obsolete today.
