Consider a series LC branch which has an impedance
\(Z(s)=Ls+\frac{1}{Cs}=\frac{L(s^2+\frac{1}{LC})}{s}\)
The admittance of such a branch is
\(Y(s)=\frac{s}{L(s^2+\frac{1}{LC})}\)
Now consider two such series LC branches with different L,C values connected in parallel.
Remember: parallel branch admittances are additive
