ABSTRACT:
A pseudo-random binary sequence having a long period duration is generated by producing a plurality of respectively different first binary signal sequences, supplying at least one of the first signal sequences to at least one input of a feedback connected shift register having an original signal sequence in order to produce an interfering signal which alters the signal sequence being produced by the shift register, and interchanging the first signal sequences supplied to the shift register under the control of signals from a setting program and/or control signals derived from the signal sequences produced in the course of the process. When more than one shift register output is employed, the signals at the outputs are linked together by a logic circuit to form the pseudo-random binary signal sequence of long duration.
