Name 

Description 

 

ActualZeroPadding 

Ready only. Returns the ratio between the original signal length and the length of the analyzed signal padded with zeros.  

 

ArOrder 

Defines the order for the autogressive spectral estimators.  

 

ComplexSpectrum 

After the first call to Update method, this property returns a pointer to the scaled complex spectrum.  

 

ConjExtend 

If True, the conjugate symmetric part of the frequency spectrum is to be computed. 

 

ConjFlip 

If True, the conjugate symmetric part of the frequency spectrum will be placed in 0.5..1.0 Fs (as returned by the FFT), and not between -0.5..0.0 Fs. 

 

CrossSpectral 

If True, calculate the cross spectrum and not the transfer function.  

 

CZT 

Holds Chirp Z-transform configuration.  

 

DCDump 

If True, the DC component will be removed from the signal prior to the transform to the frequency domain.  

 

ExpWindow 

The parameter for the exponential windowing function.  

 

Input 

Connector property to obtain a pointer to the TSignal component holding the data to be processed. 

 

Inputs 

Connector property to obtain a pointer to a list of TSignal components holding the data to be processed. 

 

LogMaxAmplt 

This is LogMaxAmplt, a member of class TSpectrumAnalyzer. 

 

Method 

Defines the method to be used for frequency spectrum estimation.  

 

OnAfterAverage 

Event triggered just after the average has been applied.  

 

OnAfterComplexSpectrum 

Event triggered just after complex spectrum has been computed, but before averaging in the complex domain.  

 

OnBeforeAverage 

Event triggered just before the average is applied.  

 

OnBeforeSpectrumType 

Event triggered just before spectrum type is aplied, but after averaging in the complex domain.  

 

Output 

This is Output, a member of class TSpectrumAnalyzer. 

 

RunningPhase 

Defines how to remove the constant (running) phase from the phase spectrum.  

 

SidelobeAtt 

Specifies the attenuation of the main sidelobe in dB. This parameter applies only, if you use the Kaiser or Chebyshev window.  

 

SpectrumScale 

The scaling factor applied to the frequency spectrum.  

 

Stats 

Defines the parameters for the averaging and statistical analysis.  

 

SupportComplexSpectra 

This is SupportComplexSpectra, a member of class TSpectrumAnalyzer. 

 

UnwrapPhase 

If True, the phase of the phase spectrum will be "unwrapped".  

 

Window 

Specifies the window type to be used. Windows decrease spectral leakage, but also decrease spectral resolution.
