Electronics (Mike Jaroch)

An impedance in which a change in current through a device changes in direct
proportion to the voltage applied to the device [12].

One of the three states of matter. It has a definite volume but no definite form (water is a liquid) [1].

Source of cooling for high-heat producing equipments, such as microwave components, radar repeaters, and transmitters [18].

A combined, simultaneous display of the amplitude and phase relationships of
two input signals on a CRT [17].

(1) A device through which an electric current flows and which changes electrical energy into another form. (2) Power consumed by a device or circuit in performing its function [1] [13].

See OUTPUT END [10].

A passive attenuator in which the loss in one direction is much greater than that in the opposite direction. One example is a ferrite isolator for waveguides that allows energy to travel in only one direction [11].

See LUMPED-IMPEDANCE TUNING [10].

The effect of a voltmeter upon the circuit being measured that results in an
inaccurate measurement. Loading effect is minimized by using a voltmeter with an internal resistance many times higher than the resistance of the circuit being measured [3].

An area of greater signal strength in the transmission pattern of an antenna [10] [18].
