spectral density of power of noises, flicker–noise, relaxation timeAbstract
Formula for calculating intrinsic noises of electronic elements in a wide frequencies range starting from f → 0 is presented here. Ways of reducing intrinsic noises in radio electronic devices in the low frequencies range and examples of using information meaning of flicker noise in practice are described.
