In a radio receiver, we generally use .............. oscillator as a local oscillator
Correct answer: D. Hartley
- A. Crystal
- B. Wien-bridge
- C. Phase-shift
- D. Hartley
Explanation
A Hartley oscillator is commonly used as a receiver local oscillator because its tuned LC circuit provides convenient frequency adjustment over the required range. Crystal oscillators are more stable but usually offer much less tuning range.
