Q. Which among the following statements is/are precise in accordance to distortionless line?
A. A lossless line is also a distortionless line
B. A distortionless line is not necessarily a lossless line
(Marks : 02)- Published on 19 Oct 15a. A is true & B is false
b. A is false & Bis true
c. Both A & B are true
d. Both A & B are false
ANSWER: Both A & B are true
The conductors in the lossless line are perfect and the dielectric medium that separates them is absolutely lossless.
Besides this, a transmission line where the value of an attenuation constant is independent of frequency & phase constant is linearly dependent on frequency.
Hence, it is obvious that a lossless line can also be a distortionless line but a distortionless line cannot be essentially a lossless line.
