← ScienceWhich outcome occurs when a waveguide's input signal exceeds capacity?
A)Increased standing wave ratio (VSWR)✓
B)Enhanced signal noise rejection
C)Complete impedance matching results
D)Maximum power handling improves much
💡 Explanation
Increased VSWR occurs because exceeding waveguide capacity causes nonlinearity effects, driving signal reflection back toward the source rather than proper transmission; therefore, VSWR increases rather than signals propagating ideally.
