What is the effect of an incorrectly adjusted speech processor?

  1. Distorted speech
  2. Excess intermodulation products
  3. Excessive background noise
  4. All these choices are correctПравильный ответ

Объяснение

Overdriving the processor clips the audio waveform, and clipping is nonlinear, creating harmonics and unwanted mixing products that appear as splatter on the transmitted signal. Excessive processor gain also raises background sound during speech pauses, so distortion, spurious products, and noise all follow from the same misadjustment.
