Abstract

　本発明は、ディジタルフィルタのフィルタ特性を容易に変更することが可能な技術を提供することを目的とする。そして、当該目的を達成するために、本発明に係る重量測定装置では、フィルタ係数演算部６が、所定の演算式を用いてフィルタ係数を求めて信号処理部５に出力する。信号処理部５はそのフィルタ係数を用いて、ディジタル信号たる計量信号ＤＳに対してフィルタリングを実行する。上記演算式は、フィルタリングの振幅特性の阻止域において減衰量を部分的に大きくすべき少なくとも一つの減衰帯域の減衰量を指定する第１パラメータと、当該少なくとも一つの減衰帯域の帯域位置を指定する第２パラメータと、阻止域の開始周波数を指定する第３パラメータとを含んでいる。
