A second condition for oscillations is____________?
Correct answer: A. A gain of 1 around the feedback loop
- A. A gain of 1 around the feedback loop
- B. No gain around the feedback loop
- C. The attention of the feedback circuit must be one-third
- D. The feedback circuit must be capacitive
Explanation
The Barkhausen magnitude condition requires the loop gain Aβ to be unity for sustained oscillations, along with zero net phase shift. A loop gain below one makes oscillations die out, while a value above one makes them grow until limited.
