🔍 Key Concepts

• FM modulation index and what it represents • Relationship between modulation index and frequency deviation • How audio input level affects the subjective sound of received audio (loudness vs pitch)

💭 Think About

• Think about what happens to the transmit signal if the modulation index is made smaller: does the carrier deviate more or less from its center frequency? • Consider whether a low modulation index would be more likely to cause distortion/instability, or simply a weaker/softer modulation effect. • Ask yourself: would a lower modulation index change how loud the audio sounds, or actually change the pitch of the voice being transmitted?

✅ Before You Answer

• Verify that modulation index < 1 in FM means under‑modulation rather than over‑modulation. • Check which of the choices describes a condition you would expect from under‑modulation (too little deviation) instead of excessive deviation (too much). • Be sure you separate the idea of audio frequency (pitch) from frequency deviation of the RF carrier; they are not the same thing.
