Topic: Analog Electronics
The configuration of given figure is a
(Figure shows an Op-amp with a series-parallel RC network in the positive feedback loop)
- A. Precision integrator
- B. Hartley oscillator
- C. Butterworth high pass filter
- D. Wein bridge oscillator
Answer: D. Wein bridge oscillator
Explanation: The circuit contains an op-amp with a series RC and a parallel RC network in its positive feedback path, which is the classic structure of a Wien bridge oscillator.
