Samples.
Samples per second—Used to express the rate at which a DAQ board
samples an analog signal.
The manipulation of signals to prepare them for digitizing.
The voltage rate of change as a function of time. The maximum slew rate
of an amplifier is often a key specification to its performance. Slew rate
limitations are first seen as distortion at higher signal frequencies.
Total harmonic distortion—The ratio of the total rms signal due to
harmonic distortion to the overall rms signal, in decibel or a percentage.
A temperature sensor created by joining two dissimilar metals. The
junction produces a small voltage as a function of the temperature.
Transistor-transistor logic.
Given a number x expressed in base 2 with n digits to the left of the radix
point, the (base 2) number 2n – x.
Volts.
Volts direct current.
Very high density cabled interconnect.
Virtual instrument—Program in LabVIEW that models the appearance and
function of a physical instrument.
Volts, input high.
Volts, input low.
