📝 Frequency Modulation(FM) during Analog to Analog conversion

Q1. What does the abbreviation FM stand for in communication systems?

💡 Difficulty: easy | ✅ Correct: B

Q2. If the amplitude of the modulating signal is doubled while the carrier frequency remains constant, how does the maximum frequency deviation change?

💡 Difficulty: medium | ✅ Correct: B

Q3. A carrier at \(100\ \text{MHz}\) is frequency‑modulated by a sinusoidal tone of \(5\ \text{kHz}\). Which pair of frequencies represents the first upper and lower sidebands generated by this modulation?

💡 Difficulty: hard | ✅ Correct: A
