• 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:

  $\frac{m_f=δ_f}{f_m}$

  Where,

  $δ_f $ is the frequency deviation and

  $ f_m$ is the modulating frequency.

• Modulation index for FM is dimensionless …
