Similarities and differences between AM and FM radio waves
How are television signals transmitted?
Television signals are transmitted by two separate carrier waves, television signals are very similar to AM and FM signals. One carrier wave contains the visual signal which is using amplitude modulation (AM) and the other carrier wave contains the audio signal which is using frequency modulation (FM). When a TV is turned on and is tuned to display a channel, the user is selecting the visual and audio carrier waves they want the TV to receive. The TV then removes the carrier waves and translates the signals into a picture and sound.
