SignalUtils::ArYuleWalkerSpectrum Function

SignalUtils Namespace

void ArYuleWalkerSpectrum(TVec *Data, TVec *aResult, int ArOrder = 40, int ZeroPadding = 8);

Computes a frequency spectrum with the autoregressive Yule-Walker method.

#NameTypeDescription
1DataTVec *
2aResultTVec *
3ArOrder = 40int
4ZeroPadding = 8int
Remarks:

Computes a frequency spectrum from Data and places the result in aResult. ArOrder is the autoregressive order used by the Yule-Walker method and zero padding factor for the FFT is defined with the ZeroPadding parameter.

void Example()
{
    Vector b, X;
    Vector Response(0);

    b = Sin(Ramp(300, TMtxFloatPrecision::mvDouble, 0, 2 * PI * 50 / 300));
    ArYuleWalkerSpectrum(b, Response, 4, 32);
    X = Ramp(Response.Length, TMtxFloatPrecision::mvDouble, 0, 1.0 / Response.Length);
