Bit error rate (BER) is used in digital telecommunication as a figure of merit for how effectively the receiver is able to decode transmitted data. In most applications, the bit error rate is more useful because it tells you how long one has to wait before encountering an error. PathFinder could best be BER = (errors received) / (bit received) Example: If the data rate is 1 Gbit/s, then it would mean 10exp9 bits are received in 1 second. Bit error ratios (BERs, sometimes called bit error rates) measure the ratio of incorrectly received bits in a data stream to the total number of bits in the stream.
