First portion of the B listing;
"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.
BEAM: A column of light. The main lobe of an antenna radiation
pattern. Also refer to the section covering Antenna Terms.
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.
BEAM SPLITTER: A device for dividing an optical beam
into two or more separate beams. Note: An example
of a beam-splitter is a partially reflecting mirror.
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 frequency produced when two signals are mixed or combined. The beat frequency equals the difference or offset between the two frequencies. 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.
Bend Radius. The minimum radius to which a cable, without tensile load, can be bent for
its lifetime without causing broken wires or fibers, a localized weakening of the fibers, or a
permanent increase in attenuation.
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.
BIAS. Difference of potential applied to a vacuum tube or transistor to establish a reference operating level.
Transistor Bias Circuit
BIAS CURRENT. Current that flows through the base-emitter junction of a transistor and is adjusted to set the operating point of the transistor. Transistor Schematics
BIAS RESISTOR. A resistor used to bias a circuit. Also refer to Bias Resistor from the resistor dictionary section.
Bifilar Winding. Two or more windings with the wire of each winding alongside the other, matching turn for turn; may be either inductive or noninductive [Relays].
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.
