The two port matrix of an 1 : n ideal transfer is 
It describes the transfer in terms of its
It describes the transfer in terms of itsAn ideal transfer having turns ratio of 1 : n is shown below.
Here
Also,
or,
Comparing equations (1) and (2) with standard transmission-parameter 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.
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 Z11 a nd Z22 of the given T-network shown below are
Comparing equations (1) and (2) with the standard z-parameter equations;
Match List-1 with List-11 and select the correct answer using the codes given below the lists:
Z-parameter equations are:
and h parameter equations are:
Converting the Z-parameter equations into h-parameter equations, we have:
and
input admittance,
As V1(s) = V2{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
Given, output 
Using partial fraction expansion, A = 1 and B = -0.5.
The Z-parameter of the two port network shown below is given by
Applying KVL in the two (oops,
