T–∏ Equivalent Networks

Two very important two-ports are the T and ∏ networks shown in Figure 9.1. Because we encounter these two geometrical forms often in two-port analyses, it is useful to determine the conditions under which these two networks are equivalent. In order to determine the equivalence relationship, we will examine Z-parameter equations for the T network and the Y-parameter equations for the ∏ network.
