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:
“yet it seems
Life scarce can cast a fragrance on the wind,
Scarce spread a glory to the morning beams,
But the torn petals strew the garden plot;
And there’s but common greenness after that.”
—William Butler Yeats (1865–1939)
