Cancellation of noise in the weighing channel output of an electronic scale due to external vibrations is achieved by use of a reference, non-weighing channel in the scale. The reference channel is exposed to the vibrations affecting the weighing channel. The average output, Aavg, of the reference channel is divided by the instantaneous output, At, thereof, and the result is multiplied by the instantaneous output, Wt, of the weighing channel to obtain a corrected output, Wavg, indicative of the weight of an article plus tare. Method and Apparatus are disclosed. Analog and Digital embodiments of the apparatus are disclosed.
