BUILT-IN TEST EQUIPMENT (BITE)—A permanently mounted device that is used expressly for
testing an equipment or system [14].
BUNCHER CAVITY—The input resonant cavity in a conventional klystron oscillator [11].
BUNCHER GRID—In a velocity-modulated tube, the grid that concentrates the electrons in the electron
beam into bunches [11].
BURNISHING TOOL—A tool used to clean and polish contacts on a relay [3].
BUS BAR—A heavy copper strap or bar used to connect several circuits together when a large current-
carrying capacity is required [4].
BYPASS CAPACITOR—A capacitor used to transfer unwanted signals out of a circuit; for example,
coupling an unwanted signal to ground. Also called a DECOUPLING CAPACITOR [8].
CABLE—Either a stranded conductor (single-conductor cable) or a combination of conductors insulated
from one another (multiple conductor cable). Small sizes are commonly referred to as stranded wire or
as cords [4].
CABLE HARNESS—A group of wires or ribbons of wiring used to interconnect electronic systems and
subsystems [14].
CAPACITANCE—The property of an electrical circuit that opposes changes in voltage [2].
CAPACITIVE REACTANCE—The opposition, expressed in ohms, offered to the flow of an alternating
current by capacitance. The symbol for capacitive reactance is X
C
[2] [9].
CAPACITOR—An electrical device capable of storing electrical energy in an electrostatic field [2].
CAPACITOR FILTER—This filter is used on extremely high-voltage, low-current power supplies and
also where the ripple frequency is not critical [7].
CAPACITOR-START MOTOR—A type of single-phase, ac induction motor in which a starting winding
and a capacitor are placed in series to start the motor. The values of XC and R are such that the
main-winding and starting-winding currents are nearly 90 degrees apart and the starting torque is
produced as in a two-phase motor [5].
CARBON MICROPHONE—A microphone in which sound waves vary the resistance of a pile of carbon
granules. May be single-button or double-button [12].
CARDIOPULMONARY RESUSCITATION—Procedure designed to restore breathing after cardiac
arrest. Includes clearing air passages to lungs and heart massage [1].
CARRIER FREQUENCY—The frequency of an unmodulated transmitter output [12] [18].
CARRIER-CONTROLLED APPROACH—A shipboard radar system used to guide aircraft to safe
landings in poor visibility conditions [18].
CARRY—(1) One or more digits, produced in connection with an arithmetic operation, that is/are
forwarded to another digit place for processing there. (2) The number represented by the digit or digits
in (1) above [13].
