What will be the phase shift of feedback circuit in RC phase shift oscillator?
A. 360o phase shift
B. 180o phase shift
C. 90o phase shift
D. 60o phase shift
Answer:A
What will be the phase shift of feedback circuit in RC phase shift oscillator?
A. 360o phase shift B. 180o phase shift C. 90o phase shift D. 60o phase shift
Explanation: The RC feedback network provide 180o phase shift and amplifier used in RC phase shift oscillator provide 180o phase shift (op-amp is used in the inverting mode) to obtain a total phase shift of 360o.
