Question

Primary advantage of a crystal oscillator is that ________.

• A. it can oscillate at any frequency
• B. it gives a high O/P voltage
• C. its frequency of oscillation remains almost constant
• D. it operates on a very low dc supply voltage

Hint:

Crystal oscillators are best when you need precise and stable frequency over time.

Answer 1

The Correct Option is C

Step 1: A crystal oscillator uses piezoelectric crystals like quartz.
Step 2: These crystals vibrate at a fixed frequency when excited electrically.
Step 3: As a result, the oscillator output:
Is highly stable
Has very low frequency drift
Is immune to temperature and aging effects
Used in clocks, watches, and microprocessors for precise timing.
