General Electronics Terms B
Bandwidth:
the measure of a range of
frequencies having upper and lower limit
Battery:
Individual cells joined
together to give the output voltage
Binary:
the counting system used in
computer logic. Two values are available - 0 and 1. A zero is
normally represented by a 0 Volt signal, and a one by a
voltage of approximately 5 Volts - as commonly used in
microcontrollers
Binary Code:
a coding scheme that
transfer information by using a series of "1s" and "Os"
that are represented, by the "ON" and
"OFF" states
Bit Stream:
the bit rate, or flow of info,
between a sender and receiver in digital transfer.
Bit:
a unit of the binary code that
consists of either a single "1" or "O."
Bus:
Used to connect euipments,
allowing them to communicate. May be digital or
analogue, including power and earth (ground)
Byte:
a unit of the binary code that
consists of eight bits.
Balanced bridge:
Scenario that occurs when a
bridge circuit is set to give a zero output.
Barrier potential
The difference of
potential that is there across a forward biased pn junction.
Base
The region that lies betwen the
emitter and collector of a bipolar junction transistor.
Battery
A DC voltage source having
two or more cells that convert chemical energy to electrical
energy.
Baud
It is the unit of symbol rate, also known as
baud rate or modulation
rate
Beta
(b) The ratio of collector
current to base current in a bipolar junction transistor (BJT).
Bias
A DC voltage applied to a
device to control its operation.
Binary
A number system having only two
symbols, 0 and 1. A base 2 number system.
Bipolar junction transistor
(BJT), A three terminal device
in which emitter to collector current is controlled by base
current.
Bistable multivibrator
A multivibrator or a latch with
2 stable
states.
Breakdown voltage
Voltage at which the breakdown
of a dielectric or insulator takes place.
Bridge rectifier
A circuit using four diodes to
provide full wave rectification. Converts an AC voltage to a
pulsating DC voltage.
Buffer
An amplifier used to isolate a
load from a source.
Bulk resistance
The natural resistance of a "P"
type or "N" type semiconductor material.
