Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of designing a filter.SOLUTION: When there is a big difference between the resonance frequency of a distributed constant reference filter including a reference coil having a winding which provides multiple pitches equal to each other in the axial direction, and a capacitor connected in parallel with the reference coil, and the frequency of a high frequency wave that must be cut off, a division position in the reference coil for dividing the reference coil into first and second coil elements connected in series, for reducing the difference, and a division distance between the first and second coil elements are determined.SELECTED DRAWING: Figure 1 【課題】フィルタを設計する方法を提供する。【解決手段】一実施形態の方法では、軸方向に沿って互いに等しい複数のピッチを提供する巻線を有する基準コイル、及び、該基準コイルと並列接続されたコンデンサを有する分布定数型の基準フィルタの共振周波数と遮断すべき高周波の周波数との間の差が大きい場合に、当該差を減少させるために基準コイルを直列接続された第１のコイル要素と第２のコイル要素に分割する該基準コイル中の分割位置、及び、第１のコイル要素と第２のコイル要素との間の分割距離が決定される。【選択図】図１
