RLC High-Pass Filter

Design from specification

Series RLC, output across L: ω₀ = 1/√(LC), Q = √(L/C)/R. Pick an approximation and cutoff; C is chosen (→ L ≈ 10 mH) and L, R are computed and rounded to the chosen E-series.

Approximation: Cutoff f_c [Hz]: Damping ζ: C [F] (optional): R series: L series: C series:
