PCI-4451/4452 User Manual
a type of signal conditioning that allows you to attenuate unwanted portions
of the signal you are trying to measure
finite impulse response—a non recursive digital filter with linear phase
an ADC whose output code is determined in a single step by a bank of
comparators and encoding logic
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.
