Syntax

public class SecondOrder

Constructors

SecondOrder(double, double)

Constructor

Declaration

public SecondOrder(double TimeBase_s, double nanValue = -9999)

Parameters

Type	Name	Description
double	TimeBase_s	The time base, the time interval between each time step of the dataset, in seconds
double	nanValue	value that is to be treated as NaN and ignored

Methods

Filter(double, double, double, bool)

Adds a single data point to the filter

Declaration

public double Filter(double signal, double FilterTc_s, double DampingZeta = 0, bool doReset = false)

Parameters

Type	Name	Description
double	signal	data point
double	FilterTc_s	filter time constant in seconds
double	DampingZeta	filter time constant in seconds(also reffered to as zeta )
bool	doReset	usually false, setting to true causes filter to reset to the value of signal

Returns

Type	Description
double

Filter(double[], double, int, List<int>)

Filter an entire time-series in one command

Declaration

public double[] Filter(double[] signal, double FilterTc_s, int order = 1, List<int> indicesToIgnore = null)

Parameters

Type	Name	Description
double[]	signal	the vector of the entire time-series to be filtered
double	FilterTc_s	filter time constant
int	order	filter order, either 1 or 2
List<int>	indicesToIgnore	for these indices the of the signal, the filter should just "freeze" the value(can be null)

Returns

Type	Description
double[]	a vector of the filtered time-series
