Television transmitters are devices that send out signals carrying audio and video content to televisions. They convert the programming from television studios into radio waves, which travel through the air. These signals can be received by antennas connected to TV sets, allowing viewers to watch their favorite shows. Transmitters can be found in various forms, including analog and digital types. Digital transmitters provide better picture and sound quality compared to their analog counterparts. They play a crucial role in broadcasting, ensuring that content reaches homes across different distances and terrains, making television accessible to a wide audience.
