The invention relates to a random signal generator (1) having at least two functional groups (2a, 2b, 2c) which each comprise a random sequence generat or (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, 8 c) 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-o r 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 th e functional groups (2a, 2b, 2c) are interconnected via data lines (13) for th e shifting of their memory contents.
