The op amp phase shifter circuit produces an output voltage with the same magnitude as the input voltage,but with a phase angle that can be varied continuously between 0° and -180°.

Question

Quizplus · Accepted Answer

The op amp phase shifter circuit is designed to allow the phase of the output voltage to be adjusted relative to the input voltage, enabling continuous variation of the phase angle from 0° to -180° without altering the magnitude of the voltage.
