01․ For distortion less line which of following relation are true

A distortionless line is one in which the attention constant α is independent of frequency while the phase constant is linearly dependent on frequency. For this line, the condition applicable is R/L = G/C or RC = LG.

02․ For a lossy transmission line, the characteristic impedance does not depend on

A transmission line is said to be lossless if both its conductor and dielectric are lossless or R = O and G = O
So characteristic impedance be,
Inductance and capacitance don't depend on the load terminating the line.

03․ The characteristic impedance of a transmission line is

The characteristic impedance of a transmission line is given as,
Where the inductance L and capacitance C are per unit lengths. These 'per unit length' values cancel out, and hence the characteristic impedance does not depend on the length of the transmission line.

04․ Which following statement are not true for line parameters R, L, G and C of transmission line

For each line LC = μ ε and G/C = σ/ε,

05․ Which statement is not correct for the transmission line parameter R, L, G and C

Generally G = 1/R. But in AC transmission line G is not equal to 1/R, where G is conductance per unit length of the conductor. It is due to the presence of dielectric medium separating the conductor.

06․ The VSWR of transmission line is

07․ The SWR on a lossless transmission line of the characteristic impedance 100 ohm is 3. The line is the terminated by

For a transmission line, reflection co-efficient,
Here Z

_{L}= 3 00 Γ_{L}= 200/400 = ½ and SWR = 3.08․ If R = 84 ohm/Km, G = 10

^{-6}mho/Km, H = 0.01 H/Km, C = 0.061 μ F/Km and frequency = 1000 Hz, then what is the value of propagation constant of the transmission lineZ = R + jω L = 84 + j2π 100 × 0.01 = 84 + j 62.83 = 104.9 ∠ 36.8° ohm/Km.
Y = G + jω C = 383.27 × 10

^{-6}∠ 89.85° mho/Km. So propagation constant by γ = √ (yz).09․ For distortion less line which of following relation are true

A distortionless line is one in which the attention constant α is frequency independent while the phase constant is linearly dependent on frequency. For this line, the condition applicable is R/L = G/C.

10․ For a lossy transmission line, the characteristic impedance does not depend on

A transmission line is said to be lossless if both its conductor and dielectric are lossless or R = O and G = O
So characteristic impedance be,
Inductance and capacitance are not depends the load terminating the line.
