MeanAveragingFilter

class MeanAveragingFilter(timeConstant: Double = DEFAULT_TIME_CONSTANT) : AveragingFilter

FIR mean averaging filter. Computes average values using a FIR (Finite Impulse Response) filter with a length equal to: ceil(1.0 / dt * timeConstant), where dt is the time interval between samples. For typical default values: dt = 0.02 (%0Hz) and timeConstant = 0.1. Consequently FIR length is 5 samples.

Constructors

MeanAveragingFilter

constructor(input: MeanAveragingFilter)

Copy constructor.

constructor(timeConstant: Double = DEFAULT_TIME_CONSTANT)

Properties

timeConstant

var timeConstant: Double

Gets a constant relative to the period between consecutive samples to determine the cut frequency of the low-pass filter. If not specified by default this is 0.1
