programmable gain instrumentation amplifier
(1) a digital port consisting of multiple I/O lines on a DAQ device
(2) a serial or parallel interface connector on a PC
programmable peripheral interface
parts per million
pullup
multiple pulses
the inherent uncertainty in digitizing an analog value due to the finite
resolution of the conversion process
signal sources with voltage signals that are referenced to a system ground,
such as the earth or a building ground. Also called grounded signal sources.
the smallest signal increment that can be detected by a measurement
system. Resolution can be expressed in bits, in proportions, or in percent
of full scale. For example, a system has 12-bit resolution, one part in
4,096 resolution, and 0.0244% of full scale.
a flat cable in which the conductors are side by side
the difference in time between the 10% and 90% points of a system's step
response
root mean square—the square root of the average value of the square of the
instantaneous signal amplitude; a measure of signal amplitude
