GAIN. Any increase in the strength of a signal. The ratio between the amount of energy propagated from an antenna that is directional
compared to the energy from the same antenna that would be propagated if the antenna were not
directional.
GAIN-BANDWIDTH PRODUCT. The number that results when the gain of a circuit is multiplied by the
bandwidth of that circuit. For an operational amplifier, the gain-bandwidth product for one
configuration will always equal the gain-bandwidth product for any other configuration of the same amplifier.
GALVANOMETER. A meter used to measure small values of current by electromagnetic or
electrodynamic means.
GAMMA. The transistor emitter-to-base current ratio in a common-collector configuration. Gamma Ray; Emissions of a specific frequency produced from sub-atomic particle interaction.
GANGED TUNING. The process used to tune two or more circuits with a single control.
GATE. As applied to logic circuitry, one of several different types of electronic devices that will provide a
particular output when specified input conditions are satisfied. Also, a circuit in which a signal switches
another signal on or off.
GATED AGC. Circuit that permits automatic gain control to function only during short time intervals.
GATED-BEAM DETECTOR. An FM demodulator that uses a special gated-beam tube to limit, detect,
and amplify the received FM signal. Also known as a quadrature detector.
GATING. The process of selecting those portions of a wave that exist during one or more selected time
intervals or that have magnitudes between selected limits. Also, the application of a specific waveform
to perform electronic switching.
GENERATOR. A machine that converts mechanical energy to electrical energy by applying the principle
of magnetic induction. A machine that produces ac or dc voltage, depending on the original design.
GERMANIUM. Symbol Ge in the periodic table. A grayish-white metal having semiconductor properties, similar to tin.
GIMBAL. A mechanical frame, with two perpendicular intersecting axes of rotation, used to support and
furnish a gyro wheel with the necessary freedom to tilt in any direction.
GLOW DISCHARGE. Discharge of electricity through a gas in an electron tube.
GRAY CODE. A positional binary number notation in which any two numbers whose difference is one is represented by expressions that are the same except in one place. Refer to the Gray Code listing for more information.
GRAMME-RING ARMATURE. An inefficient type of armature winding in which many of the turns are
shielded from the field by its own iron ring.
