313. What is the modulation index in an FM phone signal having a maximum frequency deviation of 3,000 Hz on either side of the carrier frequency when the modulating frequency is 1,000 Hz?
The modulation index in FM is calculated by dividing the peak frequency deviation by the modulating frequency; therefore, 3,000 Hz / 1,000 Hz = 3.
