Modulation depth also referred as modulation index gives the quality and strength of the transmitted signal. If the modulation index is small, the extent of variation in the carrier amplitude will be small.Accordingly the audio signal being transmitted will not be strong.Greater the depth of modulation , clearer and stronger will be the audio signal.
