quiescent operating point

quiescent operating point

[kwē‚es·ənt ′äp·ə‚rād·iŋ ‚pȯint]
(electronics)
The currents and voltages in an electronic circuit when the input signal is replaced by its average value, so that all currents and voltages can be approximated by series expansions around this point. Also known as Q point.
