Which of the following is not true for an RC phase shift oscillator?(a

1.	Which of the following is not true for an RC phase shift oscillator?(a) Not Bulky(b) Less costly(c) Effective for oscillation less than 10KHz(d) Pure sine wave output is possibleI have been asked this question in an interview.Question is from RC Phaseshift Oscillator topic in portion Oscillators of Analog Circuits
Answer» Correct option is (d) PURE sine wave OUTPUT is possible The BEST I can explain: Since only ONE frequency can fulfill barkhausen’s criteria requirement POSITIVE feedback occurs only for one frequency. Hence pure sine wave is not possible.
