什么是1/f噪声?
What is the 1/f noise?
【摘要】 在以往的工作的基础上,发现1/f噪声是一个新的相。它有一个酝酿、发育的过程,最终能否成形,取决于能否满足可信度M#的最低要求,即M#>500。这也是判别是否是1/f噪声的依据。往后还可得知,1/f噪声的熵S#值为S#=A×10-20尔格/度。S#极小,是所有1/f噪声的共性。A不同则表现了1/f的个性。
【Abstract】 On the basis of our previous work it has been found that the 1/f noise is a kind of "phase" with a developmental process.And the fact that the 1/f noise can be finally formed or not depends on if the minimum demand for reliability of M#>500 being satisfied.Moreover this is also a criterion for distinguishing 1/f noise.Subsequently,it can be learnt that the entropy of 1/f noise is S*=A×10-20 erg/K and S* is a minimum for all kinds of 1/f noise,which is their general character.But for different 1/f noise A is a variable value,which represents the individual character of 1/f noise.
