Q. One condition to be satisfied in an oscillator circuit so that stable oscillations are produced is:
✅ Correct Answer: (C)
1800 phase shift is required between the transistor input and output.
Explanation: in an oscillator a total of 3600 of phase shift is to be achieved in the entire circuit to produce oscillations. the transistor used in the oscillator circuit must produce a phase shift of 1800 to achieve stable oscillations. hence this condition has to be satisfied by the oscillator.
