and series inductors LP in alternating order. The other filter classes can be derived from it: In a high-pass filter: 1 C LP → L HP = 2 (16.35) ωB·C LP 1 L LP → C HP = 2 (16.36) ωB·L LP 222 In a band-pass filter: C → parallel resonance circuit with (16.37) LP CLP CBP = (16.38) ∆Ω ∆Ω LBP = ω1·ω 2C LP (16.39) LLP → series resonance circuit with (16.40) ∆Ω CBP = (16.41) ω1·ω 2L LP L LBP = LP (16.42) ∆Ω In a band-stop filter: CLP → series resonance circuit with
