Frequency Modulation Synthesis

FM Basics

  • When using simple sinusoidal FM, sideband sinusoidal
    partials appear around the carrier frequency, spaced
    at integer multiples of the modulation frequency.

  • The number of significant sidebands grows (nearly)
    linearly with the amount of modulation.

  • The ratio of the frequencies of the carrier and modulator
    oscillators determines the components of the spectrum.
