Bit Error Ratio (BER)
- Definition: The rate at which erroneous bits are received over a communication link, expressed as a proportion of the total number of transmitted bits.
- Expression: BER is typically represented as a ratio or fraction, such as
\(1 \times 10^{-9}\) (1 in 1 billion), indicating the number of erroneous bits relative to the total number of bits transmitted. - Significance: A lower BER indicates better system performance and reliability. Systems with high BER values may experience more data corruption and reduced quality in communication.
