ABCD parameters are used in analysis of ______.
Directions: The following items consist of two statements, one labeled as “Assertion(A)” and the other labeled as “Reason(R)”. You are to examine the two statements carefully and decide if the Assertion(A) and the Reason(R) are individually true and if so whether the reason is a correct explanation of the assertion. Select your answer to these items using the codes given below and mark your answer accordingly.Assertion (A): The Z parameters are open circuit parameters.Reason (R): The Z parameters may be measured at one terminal while the other terminal is open.
For a two-port network, the condition of Symmetry in terms of z-parameters is
