Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Frequency stability means the ability of an oscillator to maintain constant frequency with time, temperature, and supply variations.
Step 1: A crystal oscillator uses the piezoelectric property of quartz crystal.
Step 2: Quartz crystal has a very high quality factor \(Q\).
Step 3: Due to high \(Q\), the oscillator frequency remains highly stable. Therefore, the oscillator with high frequency stability is: \[ \boxed{\text{Crystal oscillator}} \]
