← TechnologyWhich impairment increases if digital signal processing uses insufficient quantization bits during down-conversion within a software-defined radio receiver?
A)Adjacent channel interference✓
B)Symbol timing synchronization
C)Carrier frequency offset
D)Phase noise suppression
💡 Explanation
Adjacent channel interference increases because insufficient quantization amplifies folding distortion during down-conversion creating spectral artifacts, therefore leading to energy spilling into adjacent channels, rather than allowing precise signal isolation at lower bit depths.
