**"Bit Error Ratio"**The ratio or bits with errors to the total number of bits detected, usually expressed as a number with an exponent to a power of 10. Used to measure the quality of a signal path.

A measure of transmission quality, expressed as a ratio. The BER indicates how many bits are errored (incorrectly received) in a given bit stream. Generally notated as a negative exponent. For example, 1 x 10E -7 indicates one out of ten million bits (1 of 10, 000,000) are in error. Although a ratio, it is commonly referred to as “bit error rate."

The ratio of the number of bits received in error to the total number of bits transmitted in a given time interval.
