Which of the following is the likely result of using a Class C amplifier to amplify a single-sideband phone signal?

  1. Reduced intermodulation products
  2. Increased overall intelligibility
  3. Reduced third-order intermodulation
  4. Signal distortion and excessive bandwidthپاسخ درست

توضیح

An SSB signal has a continuously varying envelope and needs a linear amplifier to preserve it. Class C conducts for less than half the cycle and is grossly nonlinear, so it distorts the envelope and generates intermodulation products that spread the signal well beyond its intended bandwidth.
