Test: Transmission Lines- 1 - Question 1

For a reciprocal transmission line, the three transmission parameters are given by A = 4, B = 7 and C = 5. The value of D is equal to

Detailed Solution for Test: Transmission Lines- 1 - Question 1

Since the transmission line is reciprocal, therefore,

Test: Transmission Lines- 1 - Question 2

The real part of the propagation constant shows:

Test: Transmission Lines- 1 - Question 3

In a transmission line terminated by characteristic impedance, Z0

Detailed Solution for Test: Transmission Lines- 1 - Question 3

When a transmission line is terminated by an impedance Z, then reflection coefficient are:

Here, Z0 = Characteristic impedance of transmission line.
Since Z = Z0 therefore reflection co-efficient of voltage (pv) and current (pI) both will be zero, i.e there will be no reflection of incident wave.

Test: Transmission Lines- 1 - Question 4

A symmetrical two-part network have

Test: Transmission Lines- 1 - Question 5

A pure resistance, RL when connected at the load end of a loss-less 100 Ω line produces a VSWR of 2. The RL would be

Detailed Solution for Test: Transmission Lines- 1 - Question 5

Test: Transmission Lines- 1 - Question 6

The reflection coefficient of a transmission line with a short-circuited load is 

Detailed Solution for Test: Transmission Lines- 1 - Question 6

For a short-circuited load,
reflection coefficient of voltage

and reflection coefficient of current,

Here, only option (b) matches the answer

Test: Transmission Lines- 1 - Question 7

'The characteristic impedance Z0 of a transmission line is given by (where R, L, G, C are the unit length parameters)

Detailed Solution for Test: Transmission Lines- 1 - Question 7

The characteristic impedance (Z0) of a transmission line is given by

Test: Transmission Lines- 1 - Question 8

 The standing wave ratio (VSWR) in terms of reflection coefficient ρ is given by

Test: Transmission Lines- 1 - Question 9

If a transmission line of length less than λ/4  is short circuited, it behaves as

Test: Transmission Lines- 1 - Question 10

A line becomes distortionless 

Detailed Solution for Test: Transmission Lines- 1 - Question 10

A distortionless transmission line is one in which the attenuation constant α is independent of frequency while the phase.constant β is linearly dependent on frequency.
