WSSDistribution

All Implemented Interfaces:: ReflectionConstructable, ReflectionConstructable3<SimNode,Parameters,RandomNumberGenerator>

public class WSSDistribution
extends ContinuousDistribution

WSS (Wide Sense Stationary Process)

Meaning:	Noise generator (conversion of white noise to bandwidth-limited, colored noise with the help of a filter)
Description:	White noise at the input of a filter is uniformly distributed in the interval \((-\sqrt{3}, \sqrt{3})\). Behavior is defined by \(n\) filter coefficients \(h_0, ..., h_{n-1}\) as well as the mean value \(\mu\). Condition for positive event intervals: \(\sum\limits_{i=0}^{n-1} \|h_i\| \cdot \sqrt{3} < \mu\)
Parameters:	mean value \(\mu\) filter coefficients \(h_i (i = 0, ..., n-1, n > 0)\)
Characteristic values:	auto covariance sequence: \(R_i = \sum\limits_{k=0}^{n-1-k} h_k \cdot h_{k+i} (i = 0, ..., n)\)
Parser example:	`[...].distribution = WSSDistribution [...].distribution.Mean = 2 [...].distribution.Coefficients = [0.2 0.3 -0.05]`
