There was an article in The Proceedings of the IEEE titled "1/f Noise"
twenty or thirty years ago, if memory serves. The subject index will
certainly have this article under "noise" and/or "1/f noise" or "noise,
1/f"This article gave simple ways to generate 1/f noise from a uniformly
distributed noise. The basic approach was a cascade of one-pole lowpass
filters, each with one tenth the bandwidth of the previous filter, fed
with uniform noise.
