🔍 Key Concepts

• Positive vs. negative feedback in electronic circuits • Relationship between loop gain and sustained oscillations • How an oscillator differs from a simple amplifier

💭 Think About

• In an oscillator, does the circuit need to reinforce the signal each cycle or reduce it? Think about what that implies for the type of feedback. • If the gain around the loop is less than 1, exactly 1, or greater than 1, what happens to the signal over time? Does it die out, stay the same, or grow? • Is neutralization or negative feedback normally used to stabilize and prevent oscillations, or to promote and sustain them?

✅ Before You Answer

• Identify which type of feedback (positive or negative) tends to stabilize amplifiers and prevent oscillations. • Consider the condition on overall loop gain (greater than, equal to, or less than 1) that allows a constant-amplitude oscillation instead of a decaying or exploding signal. • Ask whether "neutralized" describes a necessary condition for creating oscillations, or a method to eliminate unwanted feedback.
