← TechnologyWhich consequence results when receiver Automatic Gain Control (AGC) misinterprets noise as a low-level signal?
A)Transmission Power increase erroneously✓
B)Reduced bit error floor occurrs
C)Signal demodulation timing variation
D)Increased dynamic signal adaptation
💡 Explanation
An AGC adjusts amplification based on received signal strength; when noise is mistaken for valid signal, the AGC reduces gain excessively because it thinks the signal is strong. Therefore, actual signals are significantly attenuated, rather than dynamically compensated or correctly amplified.
