QUESTION: 1

### The two port matrix of an 1 : n ideal transfer is It describes the transfer in terms of its

Solution:

An ideal transfer having turns ratio of 1 : n is shown below. Here Also, or, Comparing equations (1) and (2) with standard transmission-parameter equations, QUESTION: 2

Solution:
QUESTION: 3

### A two port network is not reciprocal if

Solution:
QUESTION: 4

Assertion (A): Unilateral elements offer varying impedances with variations in flow of current while bilateral elements offer same impedance irrespective of flow of current.

Reason (R): If the magnitude of the current passing through an element is affected due to change in the polarity of the applied voltage, the element is called unilateral element while if the current magnitude remains the same even if the applied emf’s polarity is changed, it is called a bilateral element

Solution:
