← TechnologyWhich signal consequence occurs when adaptive delta modulation exceeds its slope overload limit in mobile telecommunications?
A)Granular noise becomes more prevalent✓
B)Signal clipping drastically reduces gain
C)Quantization error approaches zero rapidly
D)Bandwidth compresses without distortions
💡 Explanation
Delta modulation uses step approximation; exceeding slope overload means the steps struggle to track the signal because the step size is insufficient. Therefore, there’s increased granular noise, rather than improved quantization or direct signal distortion from basic clipping/compression.
