Spread Spectrum
In telecommunication and radio communication, spread-spectrum techniques are methods by which a signal (e.g. an electrical, electromagnetic, or acoustic signal) generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference, noise and jamming, to prevent detection, and to limit power flux density (e.g. in satellite downlinks).

Famous quotes containing the word spread:
“A feme may come, leaf-green,
Whose coming may give revel
Beyond revelries of sleep,
Yes, and the blackbird spread its tail,
So that the sun may speckle,
While it creaks hail.”
—Wallace Stevens (1879–1955)
