transmitters
Devices broadcasting signals
Transmitters are devices that send signals—radio waves, electrical impulses, or other forms of energy—from one location to another.
A radio transmitter broadcasts audio; a television transmitter sends video signals.
In biology, neurotransmitters are chemicals that transmit signals between nerve cells.
More broadly, a transmitter is anything or anyone that passes something along: mosquitoes as transmitters of disease, parents as transmitters of values.
