Question:

In a feedback amplifier, if the feedback voltage is in opposite phase, the gain is less than 1. Then it will:

Options:

Never work as an Oscillator

Work as an Oscillator

Not work as an Oscillator

Work as a rectifier

Correct Answer:

Never work as an Oscillator

Explanation:
If the feedback voltage is in opposite phase ie negative feedback, the gain is less than one and it can never work as oscillator. It will be an amplifier with reduced gain.
