An audio signal of amplitude 0.1 V is used in AM of a carrier wave of amplitude 0.2 V. Calculate the modulation index.

0.75 2 1.5 0.5

0.5

Modulation Index : \(\mu\) = \(\frac{A_{m}}{A_{c}}\)                                          = \(\frac{0.1}{0.2}\)                                         = 0.5
