Abstract (en)

[origin: WO0054406A1] The invention relates to a random signal generator (1) having at least two functional groups (2a, 2b, 2c) which each comprise a random sequence generator (3a, 3b, 3c), an exclusive-or gate (4a, 4b, 4c) and a memory element (5a, 5b, 5c). The exclusive-or gate (4a, 4b, 4c) of each functional group (2a, 2b, 2c) is in each case connected with one of its inputs (6a, 6b, 6c) to a random sequence signal output (7a, 7b, 7c) of the random sequence generator (3a, 3b, 3c) of the functional group (2a, 2b, 2c) and with its other input (8a, 8b, 8c) to a data output (9a, 9b, 9c) of the memory element (5a, 5b, 5c) of the functional group (2a, 2b, 2c). The output (10a, 10b, 10c) of the exclusive-or gate (4a, 4b, 4c) of each functional group (2a, 2b, 2c) is in each case connected to a data input (11a, 11b, 11c) of the memory element (5a, 5b, 5c) of the functional group (2a, 2b, 2c). The memory elements (5a, 5b, 5c) of the functional groups (2a, 2b, 2c) are interconnected via data lines (13) for the shifting of their memory contents.
