FCC Technician Exam Question Of The Day (T7B12)

Q) What does the acronym "BER" mean when applied to digital communications systems?

A) Bit Error Rate

NJ2X Notes:
The number of bit errors is the number of received data stream bits over a communication channel that have been altered due to noise, interference, distortion or bit synchronization errors.  The bit error rate (BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval.
