ISRO Electronics & Communication (ECE) 2007 - Question 51

All ISRO Electronics & Communication (ECE) papers | ISRO Electronics & Communication (ECE) 2007

In a transmission line terminated with a load equal to the characteristic impedance, the reflection coefficient is

  • A. zero
  • B. +1
  • C. -1
  • D. infinity

Answer: A. zero

Explanation: Reflection coefficient $(\Gamma) = \frac{Z_L-Z_0}{Z_L+Z_0}$. If the load matches the characteristic impedance ($Z_L = Z_0$), then $(\Gamma) = \frac{0}{2Z_0} = 0$.
