TSpectrumPeaksAnalyzer Members

The following tables list the members exposed by TSpectrumPeaksAnalyzer.

 
Name 
Description 
 
Returns the index of the newly added mark at Freq.  
 
Called by Update method, if TraceMethod is ptNone. 
 
Called by the Update method, if TraceMethod is ptAmpltHarmonics.  
 
Finds the maximum of the peak at Freq and applies interpolation.  
 
This is Assign, a member of class TSpectrumPeaksAnalyzer. 
 
This is Destroy, a member of class TSpectrumPeaksAnalyzer. 
 
This is Dispose, a member of class TSpectrumPeaksAnalyzer. 
 
Filters the peak specified with Index.  
 
Filters all peaks.  
 
Called by Update method, if TraceMethod is ptAll. 
 
Finds the largest peak on the frequency interval.  
 
Called by Update method, if TraceMethod is ptLargest.  
 
Free 
This is Free, a member of class TSpectrumPeaksAnalyzer. 
 
Called by the Update method, if TraceMethod is ptFreqHarmonics.  
 
Converts all peaks in dB. The associated spectrum must already be in logarithmic scale.  
 
this 
Default array property for the marks (=peaks) array.  
 
Called by the Update method, if TraceMethod is ptCurrent.  
 
This is TSpectrumPeaksAnalyzer, a member of class TSpectrumPeaksAnalyzer. 
 
Reestimates the order frequency and traces the peaks.  
 
Name 
Description 
 
Set this property to false, to disable peak tracing, marking, interpolating and filtering when the Update method is called.  
 
Defines the upper frequency that limits the search for peak.  
 
Defines the lower frequency that limits the search for peak.  
 
Defines the number of harmonics to be marked, if TraceMethod is ptAmpltHarmonics or ptFreqHarmonics.  
 
Defines the peak interpolation parameters.  
 
Defines the number of largest peaks to mark, when TraceMethod = ptLargest.  
 
List 
A pointer to a list of all marked peaks (= TSpectrum.Marks). Read only.  
 
Parameters for normalized amplitude.  
 
Parameters for normalized frequency.  
 
This is Spectrum, a member of class TSpectrumPeaksAnalyzer. 
 
Defines the interval centered around the current position of peak in percentage of the bandwidth, within which the new position of the peak is to be searched for.  
 
Defines the method used to trace and mark the peaks.  
 
Set this property to true, to assume that BandwidthL = 0 and BandwidthH equals the Nyquist frequency.
