	reference to the source array of x(t)
const double	timeStep
	spacing between elements of the array (used to scale the frequencies)

Detailed Description

Spectrum analysis based on Hunter's DFT method.

It determines the location of spectral lines with a high accuracy, using Hanning filtering; the backup method of Carpintero&Aguilar without filtering is used in case of a poorly resolved line

Member Function Documentation

void smile::CSpectrumAnalyzerHunter::findSpectralLines ( CSpectrum *  spectralLines, vectord *  spectrumAmplitudes = NULL  )

virtual

Frequency analysis routine: perform Fourier transform and find up to Nmax lines in the spectrum.

input is provided by the constructor in derived classes (it may consist of one-dimensional real array of x(t) for the Hunter's method, or a complex array of { x(t),v(t) } for the Laskar's method).

Parameters

[out]	spectralLines	array (must be a pointer to an existing vector);
[out]	spectrumAmplitudes	(absolute values of complex spectrum) if the pointer to this vector is not NULL

Implements smile::CBasicSpectrumAnalyzer.
