Recent investigations on the stationarity of 1/f noise

Abstract

The fluctuations of the variance of stationary Gaussian random noise with an imposed 1/f power spectrum is treated theoretically, and experiments under well-defined conditions of 1/f noise in carbon resistors and bipolar transistors are reported. The close agreement between theoretical and experimental results demonstrates that the statistical properties of 1/f noise in physical sources are fully consistent with the assumption of stationarity.
