integral control
A control action that eliminates the offset inherent
in proportional control.
isolation voltage
The voltage that an isolated circuit can normally
withstand, usually specified from input to input
and/or from any input to the amplifier output, or to
the computer bus.
K
k
kilo, the standard metric prefix for 1000 or 10
3
,
used with units of measure such as volts, Hertz, and
meters.
M
M
mega, the standard metric prefix for 1 million or
10
6
, when used with units of measure such as volts
and Hertz; the prefix for 1,048,576, or 2
20
, when
used to quantify data or computer memory.
Mbytes/s

6
bytes/sec.
N
noise
An undesirable electrical signal. Noise comes from
external sources such as the AC power line, motors,
generators, transformers, fluorescent lights,
soldering irons, CRT displays, computers, electrical
storms, welders, radio transmitters as well as
internal sources such as semiconductors, resistors
and capacitors.
O
optical isolation
The technique of using an optoelectronic transmitter
and receiver to transfer data without electrical
continuity to eliminate high potential differences
and transients.
