ABSTRACT:
An electronic scale having a load cell and a converter for providing successive digital weight signals corresponding to time-samples of the output signal. A circuit for providing a statistical approximation of actual weight produces a weight-representing signal. The latest digital weight signal provided by the converter is compared to the weight-representing signal to determine if the difference therebetween is within a predetermined range and, if so, the latest digital weight signal is added to the statistical approximation. The weight-representing signal represents either a zero weight in the absence of an object, or the weight of an object which is placed upon the load cell. A zero storage register stores the zero weight and, if a predetermined number of digital weight signals differs from the weight-representing signal, the digital weight signals included in the statistical approximating circuit is replaced by the latest digital weight signal whereupon the weight-representing signal then produced by the statistical approximating circuit is supplied to a weight storage register. The difference between the contents of the weight storage register and the zero weight register represents the net weight of the object.
