packagePSD

Information

This package contains the implemented power spectral densities, i.e. the distributions of generated frequencies in the random signal.

There are currently two different ways of shaping these frequencies:

• An interpolation method (which is readily usabale) and
• a convolution filter (which needs some review).

Contents

Name	Description

PSD_LinearInterpolation	Linear interpolation between the noise samples
PSD_Interpolation	Apply an arbitrary interpolation by convolution with a Kernel
PSD_Convolution	Apply an arbitrary filter by convolution with its impulse response
Kernels	A collection of useful kernels for the convolution filter
