A tuned circuit used to temporarily store energy. Also referred to as a parallel-resonant circuit [9].

A wire-wound, fixed resistor having one or more additional terminals along its

The condition in which warm air is formed above a layer of cool air that
is near the earth's surface [10].

A term normally used to describe compromising emanations. These emanations are unintentionally radiated signals that could disclose classified information [17].
