CAVITY WAVEMETER

An instrument used to measure microwave frequencies [16].

CELL

A single unit that transforms chemical energy into electrical energy. Batteries are made up of cells [1].

CENTER-FEED METHOD

Connecting the center of an antenna to a transmission line which is then
connected to the final (output) stage of the transmitter [10].

CENTIMETER CUBE

A unit of volume of large rectangular or square conductors. The cross-sectional
area equals 1 square centimeter with a length of 1 centimeter [4].

CHANNEL

A carrier frequency assignment, usually with a fixed bandwidth [12].

CHARACTER

A letter, digit, or other symbol that is used as part of the organization, control, or representation of information [13].

CHARACTERISTIC IMPEDANCE

The ratio of voltage to current at any given point on a transmission line represented by a value of impedance [10].

CHARGE

Represents electrical energy. A material having an excess of electrons is said to have a negative charge. A material having a shortage of electrons is said to have a positive charge [1].

CHARGE CYCLE

The period of time that a capacitor in an electrical circuit is storing a charge [2].

CHOKE

An inductor used to impede the flow of pulsating dc or ac by means of self-inductance [6] [7].
