16.6 RECIPROCITY AND SYMMETRY IN TWO-PORT NETWORKS
We had discussed Reciprocity Theorem for memoryless circuits in Sect. 5.7 of Chap. 5. The first two forms of the theorem are reproduced below for ease of reference.
‘The ratio of voltage measured across a pair of terminals to the excitation current applied at another pair of terminals is invariant to an interchange of excitation terminals and response terminals in the case of a linear time-invariant resistive circuit with no independent sources inside.’
Various forms of Reciprocity Theorem.
‘The ratio of current measured in a short-circuit across a pair of terminals to the excitation voltage applied at another pair of terminals is invariant to an interchange of excitation terminals and response ...
