Abstract:
A method to generate a random sequence signal, comprising providing at least two non-deterministic random sequence generators (3a, 3b, 3c) from which at least two random sequence signals are generated,a) determining one random signal value from each random sequence signal of the individual random sequence generators (3a, 3b, 3c) and exclusive-or combining the one random signal value with a stored value that is allocated to another random sequence generator. (3a, 3b, 3c), b) intermediately storing a result of the combination of the random signal value and the stored value on each occasion as a new stored value, allocated to the first-mentioned random sequence generator (3a, 3b, 3c), c) repeating the steps a) and b) at least once more, d) and afterwards emitting the stored values allocated to each individual random sequence generator (3a, 3b, 3c) as a random signal.
