(computer science)
A time pulse generator found in some equipment, such as a card punch.
(electronics)
A transistor region from which charge carriers that are minority carriers in the base are injected into the base, thus controlling the current flowing through the collector; corresponds to the cathode of an electron tube. Symbolized E. Also known as emitter region.

emitter

A device radiating in usable visible, IR (infrared), or RF (radio frequency) wavelengths.
