Name 
Description 
 
Set active to false to suppress the propagation of the Pull request and the subsequent call to the Update method. 
 
Stores the amplitude of the spectrum. 
 
Holds the parameters for the frequency bands.  
 
Returns the bandwidth of the spectrum in [Hz]. 
 
Set this property to true, to request computation using complex numbers.  
 
If True, the component will pass on the udpate request to the connected component. 
 
Dt 
Returns the distance in seconds between two consecutive samples of the signal on which the frequency spectrum is based. 
 
may not have default to allow switching of default precision 
 
Set this property to true to lock changes to FloatPrecision property.  
 
Defines number of harmonics to be used when calculating statistical parameters from the amplitude spectrum. 
 
Returns the frequency resolution in Hz. 
 
Specifies Input for the data to the component.  
 
may not have default to allow switching of default precision 
 
Defines the length of the spectrum.  
 
If true, the stored spectrums will be converted to Logarithmic scale.  
 
Defines the span of the logarithmic spectrum in dB.  
 
Defines the width of the main lobe. Each frequency component in the frequency spectrum should theoretically be infinitely thin. 
 
Maximum number of spectrums up to which the spectrogram will grow.  
 
Specify value other than 0 to indicate the final frequency of the reduce bandwidth.  
 
Specify value other than 0 to indicate the start of the reduced bandwidth.  
 
The event is triggered after the call to the Update method. 
 
If assigned, this event will be called instead of a call to Bands.Update method.  
 
The event is triggered just before the call to the Update method. 
 
The event is triggered after the OnAfterUpdate event. Use this event to update any associated charts or graphs or result tables. 
 
If the Input property is not assigned, the component will call OnGetInput. 
 
The event is called after a call to InternalUpdate, OnAfterUpdate and OnDisplayUpdate from within the Update method. 
 
The event is triggered when ParamUpdate method is called. The ParamUpdate method is usually called by component editors when a value was changed by the user and the editor was "Live".  
 
If assigned, this event will be called instead of a call to Peaks.Update method.  
 
Pointer to the component that manages peak analysis.  
 
Stores the phase of the spectrum.  
 
This property determines how to handle the phase of the frequency spectrum. 
 
Specify the range of the phase spectrum. 
 
Defines the units of phase. (radian, degrees). 
 
Holds the parameters needed to generate a spectrum analysis report. Requires that the descriptor property is properly filled up.  
 
Defines the sampling frequency of the signal on which the frequency spectrum is based. 
 
Defines the length of the signal on which the frequency spectrum is based in seconds. 
 
Time in seconds between consecutive spectrums.  
 
Sampling frequency with which the spectrums are being sampled. When setting this property Dt is automatically updated.  
 
Specifies to track only marked peaks without entire spectrums.  
 
Defines the level of zero padding of the source signal.
