The bit error rate or bit error ratio (BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. BER is a unitless performance measure, often expressed as a percentage.
The bit error probability pe is the expectation value of the BER. The BER can be considered as an approximate estimate of the bit error probability. This estimate is accurate for a long time interval and a high number of bit errors.

Famous quotes containing the words bit, error and/or rate:
“The machine is impersonal, it takes the pride away from a piece of work, the individual merits and defects that go along with all work that is not done by a machinewhich is to say, its little bit of humanity.”
—Friedrich Nietzsche (18441900)
“Children, then, acquire social skills not so much from adults as from their interactions with one another. They are likely to discover through trial and error which strategies work and which do not, and later to reflect consciously on what they have learned.”
—Zick Rubin (20th century)
“I dont know but a book in a mans brain is better off than a book bound in calfat any rate it is safer from criticism. And taking a book off the brain, is akin to the ticklish & dangerous business of taking an old painting off a panelyou have to scrape off the whole brain in order to get at it with due safety& even then, the painting may not be worth the trouble.”
—Herman Melville (18191891)
