Question 1
What is the necessary condition for sustained oscillations according to the Barkhausen Criterion?
- |Aβ| < 1
- |Aβ| > 1
- |Aβ| = 1
💡 Hint: Think about stability in oscillation.
Question 2
True or False: If the total phase shift around the loop is not an integer multiple of 360 degrees, oscillations will be sustained.
- True
- False
💡 Hint: Reflect on the importance of phase.

Challenge Problems
Push your limits with challenges.
Question 1
If an oscillator has a gain of 25 and its feedback network attenuates the signal to 0.04, what is the loop gain? Will this oscillator sustain oscillation?
💡 Hint: Remember the loop gain formula.
Question 2
Explain how varying the feedback network can affect both the gain and the phase in an oscillator circuit.
💡 Hint: Consider examples of components in the feedback network.
