What is a Transmitter?
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device that produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna.

What does a transmitter do?
In the Telecommunications world, a Transmitter is a device that produces radio waves radiating from an antenna. In the world of process control, a Transmitter is a device that converts the signal produced by a sensor into a standard instrumentation signal representing a process variable being measured and controlled.
Does a transmitter need electricity?
All data transmission requires power because the transmission itself—whether that is radio, visible light, or sound—carries energy. Without a power source, that energy would be “free” and that would violate the second law of thermodynamics.
How does a transmitter produce a signal?
How a transmitter sends radio waves to a receiver. 1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the waves arrive at the receiver antenna, they make electrons vibrate inside it.
