JPH0621814B

A digital filter or an equivalent device for filtering a weight signal provided by a weighing device to remove undesirable oscillatory components caused by mechanical vibration of the weighing device, which is constructed to have a plurality of notch frequencies in its transfer characteristic within and/or near the frequency range including such undesirable oscillatory components by utilizing the principle of transfer function of multiplex progressive averages of a series of sample values extracted from the weight signal.
