1/f Noise - the Flickering Candle |
Here
is a good short tutorial on
1/f noise from the EDN website. Says TI's Bruce Trump, in part,
"It's also called flicker noise, like a flickering candle. Seen on an
oscilloscope with a slow sweep it has a wandering baseline (figure 1)
because the high frequency noise rides on larger low frequency content.
Pink noise, another metaphoric name, also suggests the stronger low
frequency component. Flicker noise seems ever present in physical systems
and life science. Weather/climate patterns, for example, have a 1/f
component..."
