Abstract
It is an object of the present invention to provide techniques which allow for easier change in filter characteristics of a digital filter. Then, in order to attain this object, in a weighing device according to the present invention, a filter coefficient calculator () calculates a filter coefficient using a predetermined mathematical expression and outputs the result to a signal processor (). The signal processor () carries out a filtering process on a weight signal (DS) of a digital signal using the filter coefficient. The mathematical expression includes a first parameter which specifies an amount of attenuation in at least one attenuation band where attenuation should be locally intensified in a stopband of amplitude characteristics of the filtering process, a second parameter which specifies the band position of the at least one attenuation band, and a third parameter which specifies a starting frequency of the stopband.
