1. Method of measuring bit error rates of binary digital signals, in which a gate timing signal is extracted in a digital gate timing circuit from the clock pulse regenerated from the time- and amplitude-discriminated digital information, which gate timing signal is fed to in each case one input of detectors, whose numbers correspond to the number of digital signals present, the input of which is driven by a binary digital signal, and in which the output signals of the detectors are then fed as error signals to a subsequent counter which is reset by a periodic digital signal corresponding to the measuring time, and the output signal of which drives further switching elements, characterized in that the detectors (4, 5) consist in each case of a D-type flip-flop, the clock input of which is driven in each case by a binary data signal and the D-input of which is driven by the gate timing signal, and the output signal of the counter (7) downstream of the detectors (4, 5) drives a retriggerable monostable multivibrator (9) whose holding time is greater than the measuring time.
