Abstract :
A truly random sequence of numbers has an asymptotically flat Walsh power spectrum. This fact is used to devise a new test for the randomness of the output of random number generators. Because it takes little computing time to obtain the Walsh power spectrum of even very long sequences, generators with large periods can be tested. Some computed examples are shown.
