  • Modulation index is defined as the ratio of the maximum frequency deviation to the modulating frequency.

  • Modulation index for FM is always more than one. It is given as:

    mf=δf/fm

    Where,

    δf is the frequency deviation and

    fm is the modulating frequency.

  • Modulation index for FM is dimensionless quantity and …
