Operational Simulation of LC Ladder Filters
One form of this technique is called Leapfrog Technique
Fundamental Building Blocks are
- Second-order Realizations
There are two main approaches for implementing highorder filters:
- Multiple Feedback Architecture: Leap Frog, Follow the
T(s) = Ti (s)
s 2 + Cis + d i
where Ti (s) = K i
s 2 + o s + 2
