| Abstract(in English) | FIR digital filters composed of parallel multiple subfilters are proposed. A binary expression of the input signal is decomposed into multiple shorter words, which drive the subfilters having different length. The output error is evaluated by mean squared and maximum spectra, and can be made much smaller compared to conventional filters. A fast algorithm is also proposed to determine optimal filter lengths and coefficients of subfilters. Many examples confirm that the proposed filters generate smaller output errors than conventional filters under the condition of specified number of multiplications and additions in filter operations. |
