Is flicker noise a statistical stationary process? (Read 3449 times)

greatqs Junior Member Offline Posts: 11	Is flicker noise a statistical stationary process? Nov 09^th, 2006, 5:08am I'm really interested in the mathematical definition of flicker noise. Suppose flicker noise is a random process. question is whether it is a stationary process, wide-sense stationary process or non-stationary process? thanks a lot.

However, as my knowledge of random processes is now rusty, here is a link which might help you: http://www.astro.virginia.edu/class/bradley/astr535/noise.pdf Regards Vivek

If you have can access IEEEXplore, you also could have a look at M.S. Keshner, "1/f noise", proc. IEEE, vol. 70, p. 212, Mar. 1982 Cheers, Paul
