Definition of sideband in English: sidebandnoun ˈsʌɪdbandˈsīdˌband Telecommunications Each of two frequency bands either side of the carrier wave, which contain the modulated signal. 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.
