All 'psuedoramdom' generators are predictable, that doesn't make them less 'good', except for cryptographic applications. > but in this case all thats required is that it > produces noise that is approximatly white (ie. equal energy in each > frequency band), and its efficient. It's a perfectly good choice for this application. Its only problem is when you use it to generate random *bits*. Witm m = 2^N, the lower n bits will form of cycle of lenght 2^n, so e.g. the LS bit is just altermating 0,1,0,1,0,1 -- not very random. -- FA
