A television transmitter is a device that sends out television signals over the airwaves. It converts audio and video signals from a TV station into radio waves, which can be picked up by TV antennas and received by televisions. This process allows viewers to watch their favorite shows and broadcasts from various channels. Transmitters come in different power levels and types, including analog and digital. Digital transmitters provide better picture and sound quality compared to their analog counterparts. They play a crucial role in broadcasting, ensuring that signals reach homes and devices across a wide area, making television accessible to many people.
