active component (redirected from Passivity (engineering))

active component

A device that adds intelligence in some manner to the signal or data that passes through it. For example, in networking, an active hub regenerates fading input pulses into new, strong output pulses. In contrast, a passive hub is just a junction box that does not affect the passing data.
