← TechnologyWhich modulation outcome occurs when clipping a 64-QAM RF signal?
A)Increased bit-error rate (BER)✓
B)Decreased spectral efficiency
C)Optimized constellation diagram shape
D)Enhanced signal-to-noise ratio (SNR)
💡 Explanation
Clipping introduces harmonic distortion, thereby increasing the bit-error rate due to compromised signal integrity. Error vector magnitude (EVM) measures said integrity because it correlates directly with BER rather than the efficiency, shape, or SNR under those conditions.
