Calculate modulation index of an FM sign...

Calculate modulation index of an FM signal in which modulating frequency is 2 k Hz and maximum deviation is 10 k Hz.

Verified by Experts

The correct Answer is:

5

Here, `v_m` = 2k Hz, `delta_("max") = 10k` Hz
As `m_f = delta_("max")/(v_m) :. m_f = 10/2 = 5`.
