The generation and recognition of flicker noise

Flicker noise is defined as noise whose power spectral density var ies inversely proportional to the Fourier frequency. electronic devicej but comprehensive explanations as to its source and level are lacking. approximate flicker noise by analog methods which a r e amenable to the use of analog computers. cer ta in diffusion processes and certain Poisson processes can generate flicker noise. using a digital computer is presented. Flicker noise appears to be present in every It is shown that one can It is also shown that A method of generating flicker noise With a little practice one can learn to recognize noise processes with various power law spectra--some examples a r e shown. spectral density from time domain measurements which have been developed recently by several authors is presented.
