ETYM Latin annuntiator.
Indicates which electrical circuit has been active.
One that annunciates; specifically; a usually electrically controlled signal board or indicator.

In transistors, the region that serves as a source of charge carriers. Compare base (definition 3), collector.
The electrode in a transistor where electrons originate.

Someone who communicates by signals; SYN. signaller.

A device that converts one form of energy into another. Electronic transducers either convert electric energy to another form of energy or convert nonelectric to electric energy.
A device that converts one form of energy into another.
A device (or medium) that converts energy from one form to another. The term is generally applied to devices that take physical phenomenon (pressure, temperature, humidity, flow, etc.) and convert it to an electrical signal.
Electronic device transmitting received energy in a different form.
Device that converts one form of energy into another. For example, a thermistor is a transducer that converts heat into an electrical voltage, and an electric motor is a transducer that converts an electrical voltage into mechanical energy. Transducers are important components in many types of sensor, converting the physical quantity to be measured into a proportional voltage signal. + prikaži više
