Statement I: Class B stages produce crossover distortion.
Statement II: Class A stages produce crossover distortion.
In the light of the above statements, choose the correct answer.
Answer: D
The first is true and the second is false: a class A device never stops conducting, so there is no handover and no gap in the transfer characteristic. Crossover distortion is the price of splitting the cycle between two devices, and class A pays a much larger price in efficiency instead to avoid it. Each class's characteristic defect follows directly from its conduction angle, which is why the angle is the first thing to establish.
