Class GaussianNoise

java.lang.Object

org.epics.pvmanager.sim.GaussianNoise

public class GaussianNoise
extends Object

Function to simulate a signal that has a gaussian distribution. The warning limits are set above the standard deviation and the alarm above two times the standard deviation. The total range is 4 times the standard deviation. All values are going to have no alarm status, with the timestamp set at the moment the sample was generated.
