Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What must the loop gain be for an oscillator to sustain oscillation?
- < 1
- = 1
- ≥ 1
💡 Hint: Think about what happens if the gain is less than one.
Question 2
In positive feedback, the feedback signal must be in phase with the input signal.
- True
- False
💡 Hint: Consider what happens to feedback when signals are out of alignment.
