Frequency conversion
Encyclopedia
Frequency conversion may refer to different processes affecting frequency of physical phenomena:
- A frequency changerFrequency changerA frequency changer or frequency converter is an electronic device that converts alternating current of one frequency to alternating current of another frequency. The device may also change the voltage, but if it does, that is incidental to its principal purpose.Traditionally, these devices were...
is an electronic device that converts alternating current (AC) of one frequency to alternating current of another frequency.- A variable-frequency drive is a type of frequency changer
- Frequency conversion in nonlinear opticsNonlinear opticsNonlinear optics is the branch of optics that describes the behavior of light in nonlinear media, that is, media in which the dielectric polarization P responds nonlinearly to the electric field E of the light...
may refer to various manipulations of the frequency of light. - A Hetrodyne is used in signal electronics to convert frequencies.
