← TechnologyWhich distortion arises when limited DSP resolution improperly reconstructs a QAM communication signal?
A)Quantization Noise Increase✓
B)Inter-Symbol Interference Growth
C)Carrier Frequency Drifting
D)Phase Modulation Instability
💡 Explanation
Quantization Noise Increase emerges from digital signal processing performing discrete approximations. Imperfect reconstruction causes additive noise because the limited resolution misrepresents the original analog signal, therefore increasing quantization noise rather than distorting the signal shape.
