a component that initiates communication with other components
a VisualWorks component whose widget is a View and has a Model and a Controller
Electronic components that can operate on an applied signal, such as transistors and diodes.
A component that provides gain or amplification such as transistor, integrated circuit, valve - such as a triode value. (See passive for opposite)
A component that provides gain or amplification such as transistor, op-amp, or integrated circuit.
A component which adds energy to the signal it passes, e.g., transistors, rectifiers, diode, amplifiers, oscillators, mechanical relays and almost all IC’s.
An electronic component whose parametric characteristics change while operating on an applied signal.
circuit element that switches the flow of current or has gain. Example are: transistors, diodes, vacuum tubes, etc.
In electronics, an active component is one that can be used to provide gain in an electronic circuit.
