Page 30: Filter Parameters
SCT-1100 Weight Transmitter 4.4.1 Filter Parameters Standard digital filtering uses mathematical averaging to compensate for the noise that the A/D converter sends periodically because of external vibration. This filter compensation makes data less susceptible to a DC signal bias error for some signals. Each of the filters of the SCT-1100 are intended to compensate for different types and intensities of digital noise and vibration. -
