Question:
The envelope detector is
The envelope detector is
Show Hint
Envelope detector is simplest AM demodulator.
Updated On: Jul 2, 2026
- asynchronous detector
- synchronous detector
- coherent detector
- product demodulator
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Envelope detector recovers modulating signal without carrier synchronization.
Step 1: Working principle Uses diode and RC circuit.
Step 2: No phase reference Does not require carrier phase information.
Step 3: Asynchronous nature Operates independently of carrier phase.
Step 4: Compare Synchronous detectors need carrier reference.
Step 5: Conclusion \[ \boxed{\text{Asynchronous detector}} \]
Final Answer: \[ \boxed{(A)} \]
