Television signals are the invisible waves that carry audio and video content from a broadcasting station to your TV. These signals can be transmitted in different ways, such as through cable, satellite, or over-the-air antennas. When you turn on your TV, it picks up these signals and converts them into the shows and movies you enjoy. There are two main types of television signals: analog and digital. Analog signals were the traditional way of broadcasting, but they have mostly been replaced by digital signals, which provide better picture and sound quality. Digital signals also allow for more channels and features, enhancing your viewing experience.
