Each of two frequency bands either side of the carrier wave, which contain the modulated signal.
〔电信〕边频带，旁频带
Example sentencesExamples
Tone-induced by-products may involve quantizing noise, harmonic distortion and any amplitude or phase modulation sidebands falling outside the reject limits of the notch filter.
In signal recycling it is these sidebands that are stripped off the laser carrier wave and sent back into the interferometer, so that the signal can be built up and amplified.
The carrier itself is never really set - only the modulation products of the sidebands - so that the methods for measuring power change a bit from analog.
The origin bands are usually described as bands, whereas the sidebands are labeled.
If you go offshore, you may need modems and programs that work with a single sideband or HAM radio, and/or a satellite phone for data transmissions.
