In a Frequency Modulation (FM) system, how is the output signal-to-noise ratio affected by increasing the frequency deviation?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1Noise effects decrease because the signal-to-noise ratio improves with higher deviation.✓
- 2Noise effects increase proportionally as deviation scales up.
- 3Noise impact remains completely constant and independent of frequency deviation.
- 4Noise decreases only when the frequency deviation is kept minimum and close to zero.
Correct answer
Noise effects decrease because the signal-to-noise ratio improves with higher deviation.
