← ScienceWhich outcome occurs when a cable modem's signal experiences significant multipath propagation?
A)Reduced bandwidth at delivery point✓
B)Increased signal-to-noise ratio appears
C)Improved forward error correction ensues
D)Enhanced quadrature amplitude modulation
💡 Explanation
Reduced bandwidth transmission occurs because multipath propagation causes constructive and destructive interference due to varied path lengths of the radio waves; therefore bandwidth is reduced, rather than alternatives like noise or error correction that do not directly address signal interference.
