Extra exam question E7G05
Subelement E7, PRACTICAL CIRCUITS· Group E7G
How can unwanted ringing and audio instability be prevented in an op-amp audio filter?
- A.Restrict both gain and Q (correct answer)
- B.Restrict gain but increase Q
- C.Restrict Q but increase gain
- D.Increase both gain and Q
WhyUnwanted ringing and instability in an op-amp audio filter are prevented by restricting both gain and Q. Unwanted ringing and instability in an op-amp audio filter are prevented by restricting both the circuit's gain and its Q, since pushing either one too high increases the circuit's tendency to overshoot and oscillate around its intended response, answer A. Increasing either gain or Q, or restricting only one while raising the other, moves in the wrong direction and makes ringing and instability more likely, not less.
