SignalUtils::MovingAverageFilter Function

SignalUtils Namespace

void MovingAverageFilter(TVec *Data, int MaskSize, int DataIndex = 0, int Len = - 1);

Filter data with a moving average filter.

#NameTypeDescription
1DataTVec *
2MaskSizeint
3DataIndex = 0int
4Len = - 1int
Remarks:

Applies moving average filter to Data from DataIndex to DataIndex+Len. Set Len to -1 to use the full Data length. MaskSize defines the length of the filter in samples. This MovingAverageFilter routine can be used to filter a block of data (not for streaming).

Examples
#include "MtxExpr.h"
#include "Units.SignalUtils.h"

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Signal;
using namespace Dew::Signal::Units::SignalUtils;

void Example()
{
    Vector b(0);
    Vector c(0);

    b.Size(300);

    Tone(b, 300, 5.0 / 300, 0, 1, false);
    c.Copy(b);
    MovingAverageFilter(b, 20, 0, MtxVecEOA); //from Index 0 to EndOfArray
}
