filtering a type of signal conditioning that allows you to attenuate unwanted portions
of the signal you are trying to measure
FIR finite impulse response—a non recursive digital filter with linear phase
flash ADC an ADC whose output code is determined in a single step by a bank of
comparators and encoding logic
floating signal sources 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.
