SHAPING CIRCUIT

A circuit that alters the shapes of input waveforms [9].

SHARP-CUTOFF TUBE

The opposite of a remote-cutoff tube. An electron tube that has evenly spaced
grid wires. The amplification of the sharp-cutoff tube is limited by the bias voltage and tube characteristics [6].

SHELF LIFE

The period of time that a cell or battery may be stored and still be useful [1].

SHIELDED PAIR

A line consisting of parallel conductors separated from each other and surrounded by a solid dielectric [10].

SHIELDING

(1) A metallic covering used to prevent magnetic or electromagnetic fields from affecting an object [1]. (2) Technique designed to minimize internal and external interference [14].

SHORT CIRCUIT

An unintentional current path between two components in a circuit or between a component and ground; usually caused by a circuit malfunction [1] [3] [16].

SHORT-CIRCUITED LINE

A transmission line that has a terminating impedance equal to 0 [10].

SHUNT

A resistive device placed in parallel with another component. Appreciable current may flow through it and an appreciable voltage may exist across it [12].

SHUNT PEAKING

A technique used to improve high-frequency response in which a peaking coil is
placed in parallel (shunt) with the output signal path [8].

SHUNT RESISTOR

A resistor in parallel. In an ammeter, shunt resistors are used to provide multiple ranges [3].
