See attached figure.
This figure shows transmission Coefficient, |T(Ω)| of Elliptic LPF for order=7 and order=6.
Here, there are two problem for even order case.
(1) |T(Ω=0)| ≠ 1
(2) |T(Ω=∞)| ≠ ∞
As you know, we can not realize Even Order Elliptic LPF by L and C.
So frequency conversion is applied for original transmission Coefficient to overcome this problem.
T(Ω) -> T(ω)
However is this equivalent to an order reduction ?
Is there any practical value for Even Order Elliptic LPF of L and C ?
