- 1Have no effect on the amplitude or phase of the demodulated output signal.
- 2Increase the peak amplitude of the demodulated signal proportionally.
- 3Completely block and attenuate the demodulated signal to zero for all values of φ.
- 4Attenuate the output signal amplitude by a factor of cos(φ) and cause potential distortion.✓
Correct answer
Attenuate the output signal amplitude by a factor of cos(φ) and cause potential distortion.
