Q1:

A lossless 50 Ω transmission line is terminated 30 + j25 Ω, then voltage reflection coefficient and current reflection coefficient are

A 062 ∠82.88, - 0.62 ∠82.88

B 10.36 ∠11.296, - 10.36 ∠111.296

C 0.23 ∠49.1, - 0.23 ∠ + 49.1

D - 10.36 ∠111.296, 10.36 ∠111.296

ANS:D - - 10.36 ∠111.296, 10.36 ∠111.296

Voltage reflection coefficient Current reflection coefficient : ri = - rv = + 10.36 ∠111.296.
