Which challenge increases substantially in amplitude-modulated signals because of noise?

💡 Explanation

Reduced detector SNR arises due to the rectifier's increased sensitivity to noise at low signal levels; envelope distortion occurs because weak signals are more affected by additive noise, therefore the envelope is poorly reconstructed rather than PSK distortion or an inability to multiplex frequencies.
