摘要： A digital filter for a digital weigher reduces a calculation time in an adapted filter while maintaining weighing accuracy, a digital weigher includes the filter for the weigher, and a wave filtering process method uses the digital filter for the digital weigher. A fixation section of a FIR filter removes an oscillating component in a predetermined frequency range, from a digital weighing signal. A determination device determines whether an amplitude of an oscillating component contained in a digital weighing signal derived by performing a wave filtering process falls within a predetermined damping range. A control device changes a frequency range of an oscillating component to be removed by an adaptive section of the filter based on a result of the determination. The adaptive section of the filter performs the wave filtering process with respect to the oscillating component in the frequency range changed by the control device.

摘要翻译： 用于数字称重仪的数字滤波器可减少适应滤波器的计算时间，同时保持称重精度，数字称重器包括称重器的滤波器，波形滤波处理方法使用数字滤波器进行数字称重。 FIR滤波器的固定部分从数字称重信号中去除预定频率范围内的振荡分量。 确定装置确定通过执行波滤波处理导出的数字称重信号中包含的振荡分量的幅度是否落入预定的阻尼范围内。 控制装置基于确定的结果来改变由滤波器的自适应部分去除的振荡分量的频率范围。 滤波器的自适应部分对由控制装置改变的频率范围内的振荡分量执行波滤波处理。
