Home Electric Networks The Lattice Network  


The Lattice NetworkThe 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 12 and the output terminals 34, 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, Z_{12oc},_{ }Z_{12sc},_{ }Z_{34oc}.
From Fig. 11 it is seen that
and that
When these terms are inserted in equations 21, 20, and 19 in this order and when equations are simplified,^{3}
