🔍 Key Concepts

• Frequency modulation (FM) basic idea: a carrier frequency that is varied by an audio/modulating signal • In FM, what we mean by "deviation" of the carrier frequency when an audio signal is applied • How ratios are normally written: "this quantity" divided by "that quantity"

💭 Think About

• Ask yourself: in FM, when we say "frequency deviation," what specific part of the carrier’s behavior are we talking about? • Which of the options actually uses the maximum carrier frequency deviation in the numerator or denominator of the ratio? • Does a sensible definition of deviation ratio need BOTH: a measure of how far the carrier moves AND a reference to the audio (modulating) frequency?

✅ Before You Answer

• Identify which answer choice contains maximum carrier frequency deviation as one part of the ratio. • Check that the other part of the ratio is a modulating (audio) frequency, not a carrier frequency. • Eliminate any option that compares two audio frequencies with each other, or compares a carrier center frequency directly to audio frequency, because that doesn’t describe how far the carrier deviates.
