The **reflected binary code**, also known as **Gray code** after Frank Gray, is a binary numeral system where two successive values differ in only one bit. It is a non-weighted code.

The reflected binary code was originally designed to prevent spurious output from electromechanical switches. Today, Gray codes are widely used to facilitate error correction in digital communications such as digital terrestrial television and some cable TV systems.

### Famous quotes containing the words code and/or gray:

“Wise Draco comes, deep in the midnight roll

Of black artillery; he comes, though late;

In *code* corroborating Calvin’s creed

And cynic tyrannies of honest kings;

He comes, nor parlies; and the Town, redeemed,

Gives thanks devout; nor, being thankful, heeds

The grimy slur on the Republic’s faith implied,

Which holds that Man is naturally good,

And—more—is Nature’s Roman, never to be

scourged.”

—Herman Melville (1819–1891)

“Each in his narrow cell for ever laid,

The rude forefathers of the hamlet sleep.”

—Thomas *Gray* (1716–1771)
