Question

Quizplus · Accepted Answer

For a feedback oscillator to sustain oscillations, the product of the amplifier gain (AV) and the feedback factor (B) must equal one. This condition ensures that the loop gain (AV × B) is unity, allowing the oscillations to sustain indefinitely without growing or decaying.
