Creating Noise: second edition

by Stefan Hollos, J. Richard Hollos

This book provides an introduction to noise. It shows how to create noise digitally on a computer or using analog electric circuits. Many different forms of noise such as white, pink, and noise with general power spectral densities are covered.

The book shows how to design analog electric circuits that create pink noise with unity gain at any arbitrary frequency. There are analogous design procedures for generating noise on a computer.

There is much original content in this book that has not been published anywhere else as far as we know. Engineers, physicists, mathematicians and sound artists may all find something of interest.
