A study on 1/f noise spectrum generation in nonlinear transmission media and biomedical systems

Abstract We will show experimentally how the nonlinear transmission line transforms the white noise spectrum and derive the Burgers equation in the soliton transmission line with loss, using the first-order approximation. The noise spectrum will be transformed to 1/ f one from white noise in the media. We will also discuss the 1/ f fluctuation in biomedical systems.
