  • Patent number: 7129424
    Abstract: The present invention relates to a method for weighing items and in particular to a method of filtering signals representing the weight of an item. The invention is applicable in all measuring instruments which indicate an average value calculated from a signal which also has unwanted components of one or more unknown frequencies. This is, for example, the case in volumeters, ampere meters and weighing-scales. Normally, the indicated result is the average value of the signal measured for a much longer time than the expected period of the slowest frequency component. This method is well known and reliable, but has the drawback of being very slow in situations where measuring speed is of importance.
