Test: ABCD Parameters of Transmission Line - Question 1

In the circuit shown below, find the h-parameter h22.
The h-parameter h11 is 2 in given circuit

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 1

Open circuiting a-a we get V= I× 2 and I= I2/2 and V= I× 4 and I= I2/2. On solving and substituting, we get h22 = I2/V= 1/2 Ω.

Test: ABCD Parameters of Transmission Line - Question 2

In the circuit shown below, find the h-parameter h12.
The h-parameter h11 is 2 in given circuit

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 2

Open circuiting a-a we get V= I× 2 and
I= I2/2 and V= I× 4 and I= I2/2. On solving and substituting, we get h12 = V1/V= 1/2.

Test: ABCD Parameters of Transmission Line - Question 3

In the circuit shown below, find the h-parameter h21.
The h-parameter h11 is 2 in given circuit

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 3

Short circuiting b - b, h21 = I2/I1 when V= 0 and -I2 = I1/2 => I2/I1 = -1/2. So h21 = -1/2.

Test: ABCD Parameters of Transmission Line - Question 4

In the circuit shown below, find the h-parameter h11.
The h-parameter h11 is 2 in given circuit

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 4

h11 = V1/I1 |V= 0. So short circuiting b - b, V1 = I1((2||2)+1) = 2I1 => V1/I1 = 2. On substituting we get h11 = V1/I1 = 2Ω.

Test: ABCD Parameters of Transmission Line - Question 5

The hybrid parameter h21 is called?

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 5

h21 = I2/I1 |V= 0. So the hybrid parameter h21 is called short circuit forward current gain.

Test: ABCD Parameters of Transmission Line - Question 6

The hybrid parameter h11 is called?

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 6

h11 = V1/I1 |V= 0. So the hybrid parameter h11 is called short circuit input impedance.

Test: ABCD Parameters of Transmission Line - Question 7

In the circuit shown below, find the transmission parameter D.
Find the transmission parameter A in given circuit

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 7

D is a transmission parameter and is given by D = -I1/I2 |V2=0. Short circuiting b-b, I1 = 7/17 V1 and -I2 = 5/17 V1. So we get I1/I2 = 7/5. So D = 7/5.

Test: ABCD Parameters of Transmission Line - Question 8

In the circuit shown below, find the transmission parameter B.
Find the transmission parameter A in given circuit

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 8

The transmission parameter B is given by B = -V1/I2|V= 0. Short circuiting b - b, -I2 = 5/17 V1 => -V1/I2 = 17/5. On substituting we get B = 17/5 Ω.

Test: ABCD Parameters of Transmission Line - Question 9

In the circuit shown below, find the transmission parameter C.
Find the transmission parameter A in given circuit

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 9

C = I1/V2|I= 0. By open circuiting b-b we get V2 = 5 I1 => I1/V2 = 1/5. On substituting we get C = I1/V= 1/5 Ω.

Test: ABCD Parameters of Transmission Line - Question 10

In the circuit shown below, find the transmission parameter A.
Find the transmission parameter A in given circuit

Detailed Solution for Test: ABCD Parameters of Transmission Line - Question 10

Open circuiting b - b, V1 = 6 I1, V2 = 5I1. On solving V1/V2 = 6/5. On substituting we get A = V1/V= 6/5.
