ABSTRACT:
A filter system for mass/weight apparatus that produces an electrical signal correlated to a mass/weight including a mechanical design for the apparatus so that the resonant vibrational frequency thereof falls above signal components of interest in the electrical signal, a fifth order low pass analog signal, and a digital low pass filter having 21/2 poles at a cut-off frequency designated so as to preserve signed characteristics in the signal of interest and significantly attenuate signal characteristics due to resonant vibrational noise.
