摘要：A transmitter-side transmission signal for compensating disturbances caused by e transmission properties of an optical transmission system is provided. A high-bit-rate-binary signal is serially introduced into an N-level-shift register. A bit pattern whose bit number depends on the transmission system disturbance influence is removed from the shift register and introduced into comparators connected to comparative-value registers. The comparative-value registers include values received from a transmission function and from various binary-bit patterns. In the comparators, the binary-bit pattern introduced is converted into a binary combination which is introduced into a digital-analog transducer, which transmits a compensation signal, corresponding to a discrete value for the amplitude or phase of the transmission signal corresponding a desired signal form, to a modulator. For bit pattern whose bit number is <=10 a code conversion is carried out a bit-data rates transmitted while the comparative-value registers of the comparators subsist with substantially slow storage elements.
