For an oscillator to properly start, the gain around the feedback loop must initially be
A. 1
B. Greater than 1
C. Less than 1
D. Equal to attenuation of feedback circuit
Answer: Option B
Solution(By Examveda Team)
In order for an oscillator to start and sustain oscillations, the gain around the feedback loop must meet specific criteria. The criteria for proper oscillation are as follows:The gain around the feedback loop must be equal to or greater than 1.
This means that the gain should be sufficient to compensate for the losses in the feedback loop, so the signal can build up and sustain itself in an oscillatory manner.
Therefore, the correct answer is:
Option B: Greater than 1
