Question

Coherent demodulation of FSK signal can be detected using

• A. Bandpass filters
• B. Bandpass filters and envelope detectors
• C. Matched filter
• D. Discriminator

Hint:

For FSK demodulation, the matched filter is optimal as it maximizes the detection efficiency and minimizes errors.

Answer 1

The Correct Option is C

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.
