# modulation factor

## Definitions

### Electronics

- 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. - synonymmodulation coefficient
- synonymmodulation depth
- synonymmodulation index
