The ratio between the modulating signal voltage and the carrier voltage is called? Correct Answer Modulation index

For undistorted modulation to occur, the voltage of modulating signal Vm must be less than the carrier voltage Vc. Therefore, the relationship between the amplitude of the modulating signal and the amplitude of the carrier signal is important. This relationship, known as the modulation index m, is the ratio m = Vm⁄Vc.
