MinAmplt 

Stores the minimum value of the Amplt spectrum found by the MinMaxAmplt method. 

 

MinPhase 

Stores the minimum value of the Phase spectrum found by the MinMaxPhase method. 

 

OnAfterUpdate 

The event is triggered after the call to the Update method. 

 

OnBandsUpdate 

If assigned, this event will be called instead of a call to Bands.Update method.  

 

OnBeforeUpdate 

The event is triggered just before the call to the Update method. 

 

OnDisplayUpdate 

The event is triggered after the OnAfterUpdate event. Use this event to update any associated charts or graphs or result tables. 

 

OnGetInput 

If the Input property is not assigned, the component will call OnGetInput. 

 

OnNotifyUpdate 

The event is called after a call to InternalUpdate, OnAfterUpdate and OnDisplayUpdate from within the Update method. 

 

OnParameterUpdate 

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".  

 

OnPeaksUpdate 

If assigned, this event will be called instead of a call to Peaks.Update method.  

 

Peaks 

Pointer to the component that manages peak analysis.  

 

Phase 

Stores the phase of the spectrum.  

 

PhaseMode 

This property determines how to handle the phase of the frequency spectrum. 

 

PhaseRange
