| Abstract(in English) | Automatically dynamic measurement systems to measure object weights are used in logistics and food industry, etc. The systems are composed belt conveyor and road cell, and is called checkweigher. Checkweighers have a problem that noises of error factor change according to speed of belt conveyor and installation surrounding. As a result, variable filters are better suited for checkweighers to reduce the noises after installation. In this report, we proposed design method of variable linear-phase FIR filters using weighted least-squares method. Proposed filter has some piecewise large attenuations in the stopband, and can change multi-factors in the stopband characteristics and some notch frequencies. The number of the polynomial coefficients increases when variable parameters are the plural number. Therefore, we show a reduction method of the polynomial coefficients. The usefulness of the proposed filter is verified through the examples. |
