To determine the rate at which errors occur or how many errors occur in any period of time,
multiply the BER by the Data Rate and scale by the amount of time. For instance to
calculate the average number of errors in an hour period: BER (errors/bit)* Data Rate
(bits/sec) * 60 secs/min * 60 min/hour. For example:
1.46E-10 errs/bit * 2.048E+06 bps * 60 secs/min * 60 min/hour = 1.08 errors/hour
