Description
取り出し手段２０（３０）の第１（第２）部分は図４に示されると共に、例えば抵抗等の第１（第２）素子２１（３１）を備える。素子２１（３１）の入力側は、キャパシタ２２（３２）および２３（３３）の直列回路を介して接地に結合され、この直列回路の共通接続点は増幅器２４（３４）の第１入力に結合され、その第２入力は接地に結合される。素子２１（３１）の入力側はさらに、キャパシタ２５（３５）および２６（３６）の直列回路を介して接地に結合され、この直列回路の共通接続点は増幅器２７（３７）の第１入力に結合される。素子２１（３１）の出力側はキャパシタ２８（３８）および２９（３９）の直列回路を介して接地に結合され、この直列回路の共通接続点は増幅器２７（３７）の第２入力に結合される。両増幅器２４，２７（３４，３７）は、負荷ライン３から取り出される複数信号を生成する。これらの複数信号は、検出手段４０（５０）の第１（第２）部分に供給される。受動素子２１（３１）の代わりに、インダクタや（部分的に）偶数の非受動素子のような他の受動素子が用いられても良いし、それゆえに、これらは排除されない。
