Abstract
Conventional electrical scales having independent weighing channels for a reference weight and the actual load with subsequent division of the resulting load signal by the reference signal to furnish the final output cannot furnish a final output signal independent of accelerating disturbances in a large critical frequency region, since changes in load change the dynamic behavior of the load channel. To substantially decrease variations in the final output signal due to such accelerating disturbances, the load signal is additionally coupled to the reference channel by means of at least one frequency-dependent network.
