| Abstract(in English) | An element value design method for RC polyphase filters having equal ripple characteristics both in passband and stopband has been proposed. A sub-optimal design method for the equal ripple characteristics has been proposed previously [2]; however, any method that gives the exact element values for the equal ripple RC polyphase filters seems to have not been reported. This report presents a numerical design method for the equal ripple RC polyphase filters, which permits any sequence of the transmission zeros. Using this method, we investigated into relations between transmission-zero sequence and element-value spread. We found that there are zero sequences with much smaller element value spread than conventional descending or sacending order of zero sequences. |
