Fast Fourier Transform – in Noise Removal

Can’t help but compare the need to remove noise with detector response to unwanted ground / background noise & "good" / wanted noise (from a target). The first is more or less random and the last consistent.

Noise removal is used to improve audio quality and allow anti noise techniques to be applied to achieve quietness. A quiet head phone when detetcing in windy conditions or when relaxing to music on a noisy airplane are applications as well.

Here is a link to how some noise removal works.



Here is another link to evolution of Digital Signal Processing for some of use who lack the in depth electronic know how.  

and another more scholarly article!
