DNL
differential nonlinearity—a measure in least significant bit of the
worst-case deviation of code widths from their ideal value of 1 LSB
dynamic range
the ratio of the largest signal level a circuit can handle to the smallest signal
level it can handle (usually taken to be the noise level), normally expressed
in decibels
E
EMC
electromechanical compliance
F
floating signal sources
signal sources with voltage signals that are not connected to an absolute
reference or system ground. Also called nonreferenced signal sources.
Some common example of floating signal sources are batteries,
transformers, or thermocouples.
G
gain
the factor by which a signal is amplified, sometimes expressed in decibels
gain accuracy
a measure of deviation of the gain of an amplifier from the ideal gain
g
rms
level of random vibration
grounded measurement
system
See SE.
H
h
hour
hardware
the physical components of a computer system, such as the circuit boards,
plug-in boards, chassis, enclosures, peripherals, and cables
hex
hexadecimal
Hz
hertz—cycles per second. Specifically refers to the repetition frequency of
a waveform.
