PCI-6023E/6024E/6025E User Manual
analog-to-digital
analog-to-digital converter—an electronic device, often an integrated
circuit, that converts an analog voltage to a digital number
the resolution of the ADC, which is measured in bits. An ADC with 16 bits
has a higher resolution, and thus a higher degree of accuracy, than a 12-bit
ADC.
analog input
analog input gate signal
analog input ground signal
analog input sense signal
a false lower frequency component that appears in sampled data acquired
at too low a sampling rate
a type of signal conditioning that improves accuracy in the resulting
digitized signal and reduces noise
American National Standards Institute
analog output
analog output ground signal
Application-Specific Integrated Circuit—a proprietary semiconductor
component designed and manufactured to perform a set of specific
functions for a specific customer
(1) hardware—a property of an event that occurs at an arbitrary time,
without synchronization to a reference clock (2) software—a property of a
function that begins an operation and returns prior to the completion or
termination of the operation
to decrease the amplitude of a signal
the range of frequencies present in a signal, or the range of frequencies to
which a measuring device can respond
