The oscillator with the best frequency stability and accuracy is
- A. Hartley oscillator
- B. Colpitts Oscillator
- C. Tickler feedback oscillator
- D. Crystal controlled oscillator
Answer: D. Crystal controlled oscillator
Explanation: Crystal oscillators utilize a piezoelectric crystal which has an exceptionally high Q-factor. This results in highly stable and accurate resonant frequencies compared to standard LC oscillators.
