Which of the following is not a requirement for oscillator operation?
A) The circuit must fulfill the Barkhausen criterion.
B) The circuit must initially be triggered into operation.
C) The feedback network must contain an RC circuit.
D) The circuit must provide positive feedback.

Quizplus · Accepted Answer

The requirement for an oscillator to operate does not specifically include that the feedback network must contain an RC circuit. Oscillators can use various types of feedback networks, including LC (inductor-capacitor) circuits, crystal oscillators, and others, depending on the desired frequency and stability. The key requirements are fulfilling the Barkhausen criterion for sustained oscillations (A), needing an initial trigger in some cases (B), and providing positive feedback to maintain oscillation (D).
