Abstract

Apparatus, methods and articles of manufacture are disclosed for modifying electromagnetic waves by reducing noise in those waves. A transfer function for a plurality of segments is derived through identifying a desired output parameter. That transfer function is then applied, via a plurality of filters or other devices, to a wave, in order to achieve said transfer function.
