The case of $$\alpha=1\ ,$$ or pink noise, is both the canonical case, and the one of most interest, but the more general form, where $$0 < \alpha \leq 3\ ,$$ is sometimes referred to simply as $$1/f\ .$$ $$1/f^ \alpha$$ noise is of interest because it occurs in many different systems, both in the natural world and in man-made processes.
