← TechnologyWhich consequence results when poor equalization sacrifices bandwidth in quadrature amplitude modulation (QAM) signal processing for digital video broadcasting?
A)Increased symbol error rate✓
B)Exaggerated group delay variation
C)Reduced amplifier back-off needs
D)Lowered intermodulation distortion floor
💡 Explanation
Increased symbol error probability occurs due to intersymbol interference amplified in poorly equalized QAM because the signal constellation points become harder to distinguish, therefore error rate rises, rather than optimizing group delay or distortion floors.
