1. efficiency is higher.
2. possible to obtain greater power output.
3. less distortion and noise interference.
4. negligible power loss at no input signal. Of these the statements:
  • a)
    2 and 3 are correct
  • b)
    1,2,3 and 4 are correct
  • c)
    1,2 and 4 are correct
  • d)
    2,3 and 4 are correct
Correct answer is option 'C'. Can you explain this answer?

The advantages of class B as compared with class A operation are1. eff...
Compared to class A operation, class B operation has
  • higher efficiency (r| = 78.5%)
  • greater output power 
  • more distortion and noise interference.
  • negligible power loss at no input signal i.e. no power drain since transistor in class B operation will not consume any power if signal is not applied.
Hence, statements 1,2 and 4 are correct.
