trans2.0

Question 1

which of the ff is not an important requirement of transmisssion line?

A. There must be minimum loss
B. There should be no stray radiation or pick-up of signal
by the line itself
C. Refraction of signal on the line must be avoided
D. Reflection of signal on the line must be avoided

Answer 1

C. Refraction of signal on the line must be avoided

Question 2

Transmission line analysis is used when, except one.

A. The frequency of operation is high
B. The frequency of operation is low
C. The length of the transmission line is long
D. The length of the line is an appreciable fraction of the
signal wavelength

Answer 2

B. The frequency of operation is low

Question 3

resistance per unit length denoted as _______.
inductance per unit length denoted as _______.
conductance per unit length ______.
capacitance per unit length _______.

Answer 3

R
L
G
C

Question 4

T o F
The line parameters R, L, G, and C are not discrete or lumped. Rather, they are distributed. By this we mean that the parameters are uniformly distributed along the entire length of the line.

Answer 4

T

Question 5

T or F

G= 1/R

Answer 5

F, G is not equal to the reciprocal of R

Question 6

the __________ of the line is the ratio of the positively travelling voltage wave to the current wave at any point on the line.

Answer 6

characteristic impedance (Zo)

Question 7

T o F
The propagation constant 𝜸 and the characteristic impedance 𝒁𝒐 are important properties of the line because both depend on the line parameters R, L, G, and C and the frequency of operation.

Answer 7

T

Question 8

a transmission line is said to be _____ if the conductors of the line are perfect (𝜎𝑐 ≈ ∞) and the dielectric medium separating them is lossless (𝜎 ≅ 0).

Answer 8

lossless

Question 9

it is one in which the attenuation constant 𝜶 is frequency independent while the phase constant 𝜷 is linearly dependent on frequency.

Answer 9
