<p>A load cell weighing device has a plurality of load cells (1a-1d). In the device, detection values are respectively output from the load cells (1a-1d). The detection values are digitized by analog-to-digital conversion circuits (3a-3d). Low frequency noise components involved in the digitized detection values are reduced by digital filters (21a-21d). Then, the noise-reduced values are summed to provide weight data.</p> |
