Television transmits moving images and sound through electromagnetic waves. An analog television receives electromagnetic signals and converts them into visible light and sound by transferring the wave energy. Digital television also receives and decodes electromagnetic signals but uses a different digital code that is converted to images on screen. Both analog and digital television receive signals transmitted through electromagnetic radiation to display pictures and audio.
