The undesirable component of the converter output voltage, usually as a byproduct of the conversion process itself. The most common form of noise is the high frequency component remaining after filtering the PWM ( see definition below) signal.
The RMS, peak-to-peak (as specified) ac component of a transducer's dc output in the absence of a measurand variation.
the rms, peak-to-peak (as specified) AC component of a sensors DC output in the absence of a change in input pressure.
