Which of the following is the likely result of using a Class C amplifier to amplify a single-sideband phone signal?
Pick an answer to check it.
Answer: D. Signal distortion and excessive bandwidth
SSB needs linear amplification because its amplitude varies. A Class C amplifier is very nonlinear, so it distorts the SSB signal and creates splatter that widens the bandwidth.
Tip: Class C is for FM and CW, not SSB.
