要約(英語): A unified design method for multiband filters using a frequency mapping approach in the classical filter design is proposed. It has previously been reported that dual band bandpass and band elimination mapping approaches are obtained by applying the bandpass or band elimination mapping twice. In this study, we examine the variation of the filter characteristics by repeating the frequency mapping, and we have found that the frequency mapping for power-of-two bands can be obtained for the filter design. We have also confirmed that not only the mapping for the power-of-two bands but the mapping for arbitrary bands including odd number bands can be obtained. The present study has demonstrated that the filter design method by using the proposed frequency mapping is very effective for the multiband filter design.
