Question

112. What is an angle of phase shift for each
designed RC network in the Phase
Shift Oscillator circuit?
(1) 30°
(2) 60°
(3) 90°
(4) 180°​

Answer 1

Phase shift of a practical RC network depends on the value of the capacitor, resistor and the operating frequency. Just by making an RC network with phase shift equal to 60° and cascading three of them together the desired phase shift of 180° can be attained.

60* is the answer
