← TechnologyWhich consequence results when intermodulation distortion corrupts digital signal multiplexing?
A)Reduced network spectral efficiency✓
B)Increased amplifier power consumption
C)Expanded guard band requirements
D)Eliminated signal propagation delay
💡 Explanation
When compounded by intermodulation, digital signals in a multiplexed system experience spectral broadening due to unwanted frequency combinations. This reduces spectral efficiency because the signals now occupy more bandwidth than originally allocated, therefore spectrum usage becomes less efficient, rather than improving it.
