🔍 Key Concepts

• Frequency deviation in FM (how far the carrier moves from its center frequency) • Modulation frequency (modulation rate) and how it affects deviation ratio • Formula for deviation ratio = (maximum frequency deviation) / (maximum modulating frequency)

💭 Think About

• What quantity goes in the numerator of the deviation ratio, and what goes in the denominator? • Are you using the maximum values given in the problem, or some average/instantaneous values? • Once you compute the ratio, is the resulting number greater than 1 or less than 1, and which answer choices are in that range?

✅ Before You Answer

• Be sure both the deviation and modulation rate are in the same units (e.g., kHz with kHz, or Hz with Hz). • Use the maximum frequency deviation and the maximum modulation rate, as stated in the question. • After calculating the ratio, compare its order of magnitude with the choices to rule out obviously incorrect answers.
