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:
“There’s Margaret and Marjorie and Dorothy and Nan,
A Daphne and a Mary who live in privacy;
One’s had her fill of lovers, another’s had but one,
Another boasts, “I pick and choose and have but two or three.”
If head and limb have beauty and the instep’s high and light
They can spread out what sail they please for all I have to say....”
—William Butler Yeats (1865–1939)
