Efficiency Factor - Data Communication

Data Communication

In data communications, the efficiency factor is the ratio of the time to transmit a text automatically at a specified modulation rate to the time actually required to receive the same text at a specified maximum error rate. All of the communication facilities are assumed to be in the normal condition of adjustment and operation. The practical conditions of measurement should be specified, especially the duration of the measurement.

Telegraph communications may have different temporal efficiency factors for the two directions of transmission.
