二维信号自然界是呈现1/f^2
三唯。。。。。。。。1/f^3
究竟是什么在制造这种长程关联的信号呢？
这种信号满足能量最小最稳定的原则吗？
与波尔滋曼分布有什么必然联系吗？ |

In W.Harrison's book Applied Quantum Mechanis. Also Mode Coupling Theory
by Gotze shows 1/f noise at higher order singularities.
Nonliner feedback+Non Markovian process+perturbative expansion

发帖数: 2 | 3 In physics system, it is believed that 1/f noise is generated by a continuou
s low activation energy distribution.
Covered the low frequency (low energy) window.
Each activation energy(a 2 level system) relates to a lorenze spectrum(a "step"
function in noise-frequency graph).(something similar to the knee in capacitance
band pass curve )
With continuous steps(flat distribution of activation energy), the slope is
1/f.
As I suggested, there are really a lot about this 1/f noise can be found in
