Question:
Coherent demodulation of FSK signal can be detected using
Coherent demodulation of FSK signal can be detected using
Show Hint
For FSK demodulation, the matched filter is optimal as it maximizes the detection efficiency and minimizes errors.
Updated On: May 5, 2025
- Bandpass filters
- Bandpass filters and envelope detectors
- Matched filter
- Discriminator
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
For coherent demodulation of Frequency Shift Keying (FSK) signals, a matched filter is used to maximize the signal-to-noise ratio (SNR) and provide efficient detection. A matched filter is designed to match the signal's characteristics, making it optimal for demodulating FSK signals.
