Interface Summary

LowPassFilter

Interface for low pass filters.

Class Summary

AdaptiveLowPassFilter	An adaptive low pass filter implementation based on the 1 Euro Filter algorithm.
ButterworthLowPassFilter	Higher order Butterworth low-pass filter implementation for filters with even an order.
ButterworthLowPassFilter.BiquadIIRBWFilter	Biquadratic IIR filter implementation of a second order Butterworth low-pass filter.
ButterworthLowPassFilter.BWFilter	Digital Butterworth filter ( as low-pass IIR filter with a Q value of 1/sqrt(2) )
ButterworthLowPassFilter.CascadedBiquadIIRBWFilter	A cascaded Biquadratic IIR filter implementation for higher even order Butterworth low-pass filters.
FilterFactory	A factory for the low pass filter for accelerometer data smoothing.
GravitationFilter	Adaption of the original android 2.3.7 gravity filter reference implementation from API-Level 10 source.
LowPassFilterAlgorithm	Static implementation of an IIR (infinite impulse response) single pole low pass filter algorithm.
NullFilter	Implementation of a null filter, which does just return the original signal.
