McqMate

Q.	One condition to be satisfied in an oscillator circuit so that stable oscillations are produced is:
A.	positive feedback is to be achieved
B.	negative feedback is to be achieved
C.	1800 phase shift is required between the transistor input and output.
D.	none of the mentioned
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.
