Increase in voltage, current
and/or power. Gain is expressed
as a ratio of amplifier output
value to the corresponding
amplifier input value.
gain bandwidth product
A device parameter that
indicates the maximum possible
product of gain and bandwidth.
The gain bandwidth product of a
device is equal to the unity
gain frequency (funity)
of the device.
gamma rays
High frequency electromagnetic
radiation from radio active
particles.
ganged
Mechanical coupling of two or
more capacitors, switches,
potentiometers, or any other
adjustable components so that
adjusting one control will
operate all.
gas
Any aeriform or completely
elastic fluid which is not a
solid or a liquid. Gasses are
produced by heating a liquid
beyond its boiling point.
geiger counter
Device used to detect nuclear
particles.
generator
Device used to convert
mechanical energy to electrical
energy.
giga
Metric prefix for 1 billion (109).
ground
An intentional or accidental
conducting path between an
electrical system or circuit and
the earth or some conducting
body acting in place of the
earth. A ground is often used as
the common wiring point or
reference in a circuit.
gunn diode
A semiconductor diode that
utilizes the Gunn effect to
produce microwave frequency
oscillation or to amplify a
microwave frequency signal.
