Reciprocity of Parameters

Reciprocity Condition in two port Parameters Reciprocity Theorem states that the two networks are said to be reciprocal of each other if the ratio of the source voltage t one port to response (current) in other branch remain unchanged upon interchanging the position of the excitation and the response From Network-1, the Response to Excitation […]
