← TechnologyWhich consequence results when receiver Automatic Gain Control (AGC) processing exceeds its compensation limit in a software-defined radio?
A)Signal clipping and distortion increase✓
B)Oscillator frequency drifting accelerates rapidly
C)Power consumption declines exponentially
D)Thermal runaway in output stage develops
💡 Explanation
Signal clipping and increase in distortion occurs because exceeding the AGC's compensation ability results in inappropriately amplifying weaker signals toward the noise floor, thus reducing receiver dynamic range. Therefore clipping increases, rather than other options, since dynamic range is compromised under such conditions.
