Which of the following is an effect of overmodulation?

  1. Insufficient audio
  2. Insufficient bandwidth
  3. Frequency drift
  4. Excessive bandwidthПравильный ответ

Объяснение

Driving a modulator past its linear range clips and distorts the modulation envelope, and the resulting distortion products appear as extra sidebands (splatter) far outside the normal channel. The signal gets wider, not narrower, so insufficient bandwidth is the opposite of what happens.
