TSignalBandpass Members

The following tables list the members exposed by TSignalBandpass.

	Name	Description
	Append	Appends Sample to the end of the signal.
	Copy	Copies signal Data and sampling frequency information.
	Crest	Compute the CREST parameter.
	Initialize	Initializes filtering structures after Factor and other properties have been set.
	InputsDirty	If all Inputs[i] are dirty the function returns true.
	InternalPull	When called, the method will pass Update requests recursively to all connected objects.
	Invalidate	Notifies all connected components that this component has fresh data.
	MarksToStrings	Convert marks to strings.
	MinMax	Find minimum and maximum amplitude and store the result in the MinAmplt and MaxAmplt properties.
	ParamUpdate	The method can be assigned to some other component even handler, as a notification that a parameter has changed and that Self should consider a recalculation.
	Peak	Find the maximum deviation of the signal from its mean value.
	PipeReset	Recursively processes all connected components backward and calls Reset method.
	Pull	Request recalculation of the entire chain of all connected components.
	PullUntilEnd	Calls Pull until pipeEnd is returned.
	Reset	Reset all delay lines.
	Size	Assign the size of the signal from Src.
	Update	Request recalculation of the data and place the result in Self.
	UpdateNotify	Call this method only, if SuspendNotifyUpdate is True.
	ValuesToStrings	Convert values to strings.

Public Properties

	Name	Description
	BandwidthH	Returns the upper bandwidth edge of the signal.
	BandwidthL	Returns the lower bandwidth edge of the signal.
	CValues	Default property to access values of a complex signal.
	Dt	Time between two consecutive samples.
	FilterDelay	Returns the filter delay in number of samples of the final sampling frequency.
	HalfBand	The bandwidth will be halved during downsampling.
	HzRes	Frequency resolution obtained, if an FFT algorithm would be run on the data.
	Input	Must be "Hidden" unless it is published
	Input	Must be "Hidden" unless it is published
	ItemNumber	Number to label the object when it is an item in the List.
	Marks	Stores the time stamps and amplitude of selected samples.
	MaxAmplt	Stores the maximum amplitude of the signal found by the MinMax method.
	MaxX	Use the MaxX property to store the time stamp (in seconds) of the right most sample.
	MinAmplt	Stores the minimum amplitude of the signal found by the MinMax method.
	MinX	Use the MinX property to store the time stamp of the left-most sample.
	PipeState	Returns the state of the pipe after the last update.
	SamplingTime	The length of the signal in seconds.
	SuspendNotifyUpdate	Set this property to True, to prevent calling OnNotifyUpdate from the Update Method.
	UsesInputs	Set it to True to indicate, that valid signals will be connected to the Input or Inputs properties.
	Values	Default property to access values of a real signal.

Published Properties

	Name	Description
	Active	Set active to false to suppress the propagation of the Pull request and the subsequent call to the Update method.
	AudioSignal	Enable when the signal processed is Audio signal.
	BandWidth	Return the bandwidth of the signal.
	ChannelCount	Get or set the number of channels multiplexed in the data property.
	Complex	Set this property to true, to request computation using complex numbers.
	Continuous	If True, the component will pass on the udpate request to the connected component.
	Data	Stores the result of the processing.
	Factor	Factor by which to change the sampling frequency of the signal connected to the Input property.
	FloatPrecision	may not have default to allow switching of default precision
	FloatPrecisionLock	Set this property to true to lock changes to FloatPrecision property.
	Input	Must be "Hidden" unless it is published
	IsDouble	may not have default to allow switching of default precision
	Length	Get or set the length of the signal in samples.
	OnAfterUpdate	The event is triggered after the call to the 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".
	Ripple	Defines the ripple of the passband and of the stopband of the FIR lowpass filter used for interpolation.
	SamplingFrequency	Defines the sampling frequency of the signal.
	ScaleFactor	Additional scaling factor which is applied without extra performance cost.
	SubBandFrequency	Defines the starting frequency of the frequency band to be extracted.
	SubBandWidth	Defines the width of the frequency band to be demodulated.
	TransBW	Defines the width of the transition band of the FIR filter used for interpolation/decimation.
