The Foster-Seeley discriminator along with amplitude limiter is called
The Foster-Seeley discriminator along with amplitude limiter is called
Show Hint
Ratio detectors provide FM demodulation and reject amplitude variations without requiring a separate limiter stage.
Updated On: Jun 25, 2026
- Envelope detector
- Ratio detector
- Balanced modulator
- Square-law modulator
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
The Ratio Detector is a modified Foster-Seeley discriminator.
It provides FM demodulation with reduced sensitivity to amplitude variations.
Step 1: Recall the relationship.
A Foster-Seeley discriminator requires an amplitude limiter before demodulation. The ratio detector incorporates this feature inherently.
Step 2: Identify the equivalent detector.
Therefore, \[ \boxed{\text{Foster-Seeley discriminator + limiter}} \] corresponds to \[ \boxed{\text{Ratio Detector}} \]
Step 3: Final Answer.
\[ \boxed{\text{Correct Option (B)}} \]
