The two port matrix of an 1 : n ideal transfer is It describes the transfer in terms of its
An ideal transfer having turns ratio of 1 : n is shown below.

or,
Comparing equations (1) and (2) with standard transmissionparameter equations,
Assertion (A): Simple resistors, inductors and capacitors are linear elements.
Reason (R): The resistances, inductances and capacitances do not change with a change in applied voltage or the circuit current.
A two port network is not reciprocal if
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
The parameters Z_{11} a nd Z_{22} of the given Tnetwork shown below are
Comparing equations (1) and (2) with the standard zparameter equations;
Match List1 with List11 and select the correct answer using the codes given below the lists:
Zparameter equations are:

in a two port network, Y_{11} is given by
The value of Z_{21}(s) in the circuit shown below is
input admittance,
As V_{1}(s) = V_{2}{s) therefore,
A two port network has zero initial conditions. At t = 0; an impulse voltage δ(t) is applied at the input producing a voltage e^{2t }+ e^{3t}) u(t) volts at the output. If the output voltage required is te^{2t} u(t) then, the input voltage will be
Given:
Input voltge,
and output,
Now, impulse response
