"B" Terms
BATTERY. A device for converting chemical energy into electrical energy. A group of two or more connected voltaic cells.Electronic Battery Manufacturers, Industrial Battery Manufacturers
BATTERY CAPACITY. The amount of energy available from a battery. Battery capacity is expressed in
ampere-hours.
BAUD. A measurement of speed based on the number of code elements or units per second. Refer to Definition of Baud.
BAY. Part of an antenna array. Antenna Definitions
BEAM-LEAD CHIP. Semiconductor chip with electrodes (leads) extended beyond the wafer.
BEAM-POWER TUBE. An electron tube in which the grids are aligned with the control grid. Special
beam-forming plates are used to concentrate the electron stream into a beam. Because of this action, the beam-power tube has high power-handling capabilities.
BEARING. An angular measurement of the direction of an object from a reference direction, such as true north.
BEARING RESOLUTION. Ability of a radar to distinguish between targets that are close together in
bearing.
BEAT FREQUENCIES. Difference and sum frequencies, which result from the combination of two
separate frequencies.
BEAT FREQUENCY. The difference between the oscillator frequency and the unknown audio frequency.
BEAT-FREQUENCY OSCILLATOR. An additional oscillator used in a receiver when it is receiving a
cw signal. It provides an audible tone. Oscillator Manufacturers
BEL. A unit of measure of ratios of power levels. The unit that expresses the logarithmic ratio between the input and output of any given component, circuit, or system. bel; [B] = log 10(P1/P2) where P1 and P2 are power levels. The dB, equal to 0.1 B, is a more commonly used unit.
BETA. The ratio of a change in collector current to a corresponding change in base current when the collector voltage is constant in a common-emitter circuit.
BEVERAGE ANTENNA. A horizontal, long-wire antenna designed for reception and transmission of
low-frequency, vertically polarized ground waves. Antenna Definitions
BIAS. Difference of potential applied to a vacuum tube or transistor to establish a reference operating level.
BIAS CURRENT. Current that flows through the base-emitter junction of a transistor and is adjusted to set the operating point of the transistor.
BIDIRECTIONAL ARRAY. An array that radiates in opposite directions along the line of maximum
radiation.
BIG-ENDIAN. A format for storage or transmission of binary data in which the most significant byte
appears first. In a multi-byte value, the byte containing the most significant bit is stored in the lowest memory
address and transmitted first, and the byte containing the least significant bit is stored in the highest memory
address and transmitted last.
