Neets Master Glossary

1-9 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 X_C 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].
