modulation factor

- A measure of the degree of modulation, usually involving the ratio of a peak variation to a steady non-peak value. The result may be multiplied by 100 to obtain a percentage.
- In
__frequency__modulation, the ratio of the peak variation of the carrier wave frequency, to the frequency of the modulating signal. The result may be multiplied by 100 to obtain a percentage. - In
__amplitude__modulation, the__peak amplitude__variation of the composite wave, to the__unmodulated carrier__amplitude. The result may be multiplied by 100 to obtain a percentage. - In amplitude modulation, the ratio of half the difference between the maximum amplitude and
__minimum__amplitude, to the__average__amplitude. The result may be multiplied by 100 to obtain a percentage. - synonym modulation coefficient
