Which of the following is the likely result of using a Class C amplifier to amplify a single-sideband phone signal?
Reduced intermodulation products
Increased overall intelligibility
Reduced third-order intermodulation
Signal distortion and excessive bandwidth✓Правильный ответ
Объяснение
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.
