Function g₀(f) = 0.2/f (linear line in logarithmic scale) shows the 1/f noise spectrum when the relaxation times are distributed as , i. e., one-by-one of the relaxation time in every two octaves; g₁(τ, f) (line with open dots) is the noise spectrum when relaxation times are arbitrarily distributed one-by-one in the range of every two octaves; g₂(τ, f) (solid line) is the noise spectrum when relaxation times are arbitrarily distributed one-by-one in the range of every decade.
