← TechnologyWhich consequence results when intersymbol interference overwhelms guard intervals in time-division multiplexing?
A)Decreased power amplifier back-off
B)Increased bit error rate occur✓
C)Reduced constellation diagram size
D)Improved spectral efficiency results
💡 Explanation
Increased bit error rate appears because intersymbol interference causes signal distortion in time-division multiplexing. The guard interval mechanism is overwhelmed, causing adjacent symbols to overlap; therefore, recovery is difficult, rather than decreased errors under ideal conditions.
