The Lattice Network

The networks (such as Fig. 4) considered in the preceding pages are known as ladder networks because of the arrangement of the series and shunt elements. Another fundamental type is the lattice network of Fig. 11. Considering only the input terminals 1-2 and the output terminals 3-4, a T (or a π) ladder network, such as Fig. 10(b), exists that is equivalent to the lattice network, and this limited equivalent network can be found from the three impedance measurements, Z12oc, Z12sc, Z34oc.
