S

SE single-ended—a term used to describe an analog input that is measured
with respect to a common ground
source impedance a parameter of signal sources that reflects current-driving ability of voltage
sources (lower is better) and the voltage-driving ability of current sources
(higher is better)
system noise a measure of the amount of noise seen by an analog circuit or an ADC when
the analog inputs are grounded
T
transducer a device that responds to a physical stimulus (heat, light, sound, pressure,
motion, flow, and so on), and produces a corresponding electrical signal
transducer excitation a type of signal conditioning that uses external voltages and currents to
excite the circuitry of a signal conditioning system into measuring physical
phenomena
V

VDC volts direct current
