Radio Transmitter Working Animation | AM and FM | Modulation A radio transmitter is a key electronic device in telecommunications that converts audio, video, or digital data into radio waves and sends them through space without the need for any physical medium such as wires. This video explains how a transmitter generates a carrier wave, adds information through modulation (AM & FM), amplifies the signal, and finally radiates it into space using an antenna. | Fadhel Mahdi
