MCQ
An oscillator is nothing but an amplifier with
- ✓Positive feed back
- BLarge gain
- CNo feedback
- DNegative feedback
✓
Answer
Correct option: A.
Positive feed back
a
(a)In oscillator, a portion of the output power is returned back $(feed \,\,back)$ to the input in phase with the starting power. This process is termed as positive feedback.
