AC
alternating current
ACH
analog input channel signal
ACH0GND
analog input channel ground signal
ADC
analog-to-digital converter—an electronic device, often an integrated
circuit, that converts an analog voltage to a digital number
ADE
application development environment such as LabVIEW,
LabWindows/CVI, Measurement Studio, Visual Basic, C, and C++
AI
analog input
AIGATE
analog input gate signal
aliasing
the consequence of sampling that causes signals with frequencies higher
than half the sampling frequency to appear as lower frequency
components in a frequency spectrum
ANSI
American National Standards Institute
AO
analog output
AOGND
analog output ground signal
ASIC
application-specific integrated circuit—a proprietary semiconductor
component designed and manufactured to perform a set of specific
functions
B
Bessel filter
a filter with a maximally flat response in both magnitude and phase. The
phase response in the passband, which is usually the region of interest, is
nearly linear. Bessel filters reduce nonlinear phase distortion inherent in
all IIR filters.
bipolar
a signal range that includes both positive and negative values
