Which impairment results when multipath interferes destructively in a wireless antenna?

A)Rapid signal amplitude fluctuations
B)Increased signal-to-noise ratio
C)Reduced intersymbol interference
D)Improved spectral efficiency

💡 Explanation

Signal fading occurs because multipath propagation causes signals to arrive out of phase, leading to destructive interference. Therefore, signal amplitude decreases rapidly, rather than experiencing enhanced signals or improved performance under these conditions.
