GATE EC 2001 Electromagnetics Solution Q 3

A transmission line is distortion less if_____.

(a) RL=\frac1{GC}

(b) RL = GC

(c) LG = RC

(d) RG = LC

Ans :- (c)

Explanation

For distornless line attenuation constant is frequency independent while phase constant is linearly dependent on frequency which is possible if,

\frac RL=\frac GC
