futils::FirstOrderFilter Struct Reference

#include <Futils.h>

Public Member Functions
	FirstOrderFilter ()
void	Reset ()
void	Init (const int dataSize, const double alpha)
std::vector< double > &	Filter (const std::vector< double > array)

Public Attributes
std::vector< double >	prevState_
std::vector< double >	filteredData_
bool	isRunning_
bool	initialised_
int	dataSize_
double	alpha_

Detailed Description

This function performs a simple 1D filtering over an array of data. The result is the output of the following function: y(i) = alpha * x(i) + ( 1 - alpha ) * y(i-1)

alpha is the 'b' output parameter of the 'ellip' MATLAB function: [b, a] = ellip(filterOrder, passbandRipple, stopbandAtt, radPerSample)

Parameters

array
size
alpha
