### C

#### COMMON-EMITTER DETECTOR

Often used in receivers to supply detected and amplified output. The emitter-base junction acts as the detector [12].

 Keyword(s): COMMON-EMITTER DETECTOR

#### COMMUTATION

The act of a commutator in converting generator output from an ac voltage to a dc voltage [5].

 Keyword(s): COMMUTATION

#### COMMUTATIVE LAW

In Boolean algebra this law states that changing the order of the terms in an
equation will not affect the value of the equation. Example: A + B = B + A; A • B = B • A [13].

 Keyword(s): COMMUTATIVE LAW

#### COMMUTATOR

A mechanical device that reverses armature connections in motors and generators at the proper instant so that current continues to flow in only one direction. In effect, the commutator changes ac to dc [5].

 Keyword(s): COMMUTATOR

#### COMPARATOR

An equipment that compares incoming signals and selects the strongest to be fed to a teletypewriter through a patch panel. This is used in diversity operation [17].

 Keyword(s): COMPARATOR

#### COMPENSATING WINDINGS

Windings embedded in slots in pole pieces, connected in series with the
armature, whose magnetic field opposes the armature field and cancels armature reaction [5].

 Keyword(s): COMPENSATING WINDINGS

#### COMPENSATION

The process of overcoming the problems associated with high frequencies in an
amplifier [8].

 Keyword(s): COMPENSATION

#### COMPLEMENT

A number or state that is the opposite of a specified number or state. The negative of a number is often represented by its complement [13].

 Keyword(s): COMPLEMENT

#### COMPLEMENT NUMBER

A number that when added to another number gives a sum equal to the base
of the number system of operation. For example, in the decimal number system, the complement of 1 is 9 [13].

 Keyword(s): COMPLEMENT NUMBER

#### COMPLEMENTARY (SECONDARY) COLORS OF LIGHT

The colors of light produced when two of the primaries are mixed in verlapping beams of light. The complementary colors of light are magenta, yellow, and cyan [10].
