Topic: Transmission Lines
A TEM mode transmission line is having distributed circuit parameters as R = 1 ohm/m, L = 200 nH/m, G = 300 µS/m, C = 60 pF, the line is:
- A. Loss-less
- B. Lossy
- C. Distortion-less
- D. None of the above
Answer: C. Distortion-less
Explanation: LG = 200 x 300 x 10^-9 x 10^-6 = 6 x 10^-11 HS/m². RC = 6 x 10^-11 FΩ/m². As LG = RC, so line is distortionless.
