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

Solution:

Since the transmission line is reciprocal, therefore,

QUESTION: 2

The real part of the propagation constant shows:

Solution:

QUESTION: 3

In a transmission line terminated by characteristic impedance, Z_{0}

Solution:

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

Here, Z_{0} = Characteristic impedance of transmission line.

Since Z = Z_{0} therefore reflection co-efficient of voltage (p_{v}) and current (p_{I}) both will be zero, i.e there will be no reflection of incident wave.

QUESTION: 4

A symmetrical two-part network have

Solution:

QUESTION: 5

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

Solution:

QUESTION: 6

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

Solution:

For a short-circuited load,

reflection coefficient of voltage

and reflection coefficient of current,

Here, only option (b) matches the answer

QUESTION: 7

'The characteristic impedance Z_{0} of a transmission line is given by (where R, L, G, C are the unit length parameters)

Solution:

The characteristic impedance (Z_{0}) of a transmission line is given by

QUESTION: 8

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

Solution:

QUESTION: 9

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

Solution:

QUESTION: 10

A line becomes distortionless

Solution:

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.
