Trying to understand quadrature fm detection I discover that a parallel Rp Lp Cp network fed from an ideal voltage source via a low value capacitor (Cs) behaves as a high pass filter with voltage gain. The resonant frequency is given by 1/ 2 Pi sqrt(L(Cp+Cs)).
Where does the voltage gain come from?
