Question

Phase shift provided by one phase shift network in RC phase shift network in 4-stage will be ___________

(a) 180 degrees

(b) 45 degrees

(c) 60 degrees

(d) 90 degrees

I have been asked this question during an interview for a job.

I want to ask this question from RC Phaseshift Oscillator in division Oscillators of Analog Circuits

Answer 1

Right choice is (b) 45 degrees

To explain: Phase shift provided by one phase shift oscillator in RC phase shift oscillator in 4 stage is 45degrees. It is 180/number of stages.
