Public Methods
 
Name 
Description 
 
Appends Sample to the end of the signal. 
 
Returns the number of samples currently stored in the buffer.  
 
Defines the length of the internal buffer in samples.  
 
Returns True, if the internal buffer has been overrun.  
 
Returns the current circular buffer read position.  
 
Returns True, if the internal buffer has been underrun. 
 
Returns the current circular buffer write position.  
 
Copy 
Copies signal Data and sampling frequency information. 
 
Compute the CREST parameter. 
 
Returns true, if there is enough data in buffer to fill Data.Length.  
 
If all Inputs[i] are dirty the function returns true. 
 
When called, the method will pass Update requests recursively to all connected objects. 
 
Notifies all connected components that this component has fresh data. 
 
Convert marks to strings. 
 
Find minimum and maximum amplitude and store the result in the MinAmplt and MaxAmplt properties. 
 
Reads Dst.Length of most recent data, without advancing the read or write cursor.  
 
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. 
 
Recursively processes all connected components backward and calls Reset method. 
 
Pull 
Request recalculation of the entire chain of all connected components. 
 
Calls Pull until pipeEnd is returned.  
 
Read 
Reads data from internal Buffer to the Data property.  
 
Reads any data still in the buffer, but less than specified Length. Missing samples become zeros.  
 
This is the overview for the Reset method overload. 
 
Size 
Assign the size of the signal from Src. 
 
Request recalculation of the data and place the result in Self. 
 
Call this method only, if SuspendNotifyUpdate is True. 
 
Convert values to strings. 
 
This is the overview for the Write method overload. 
 
Writes data to the buffer and resizes the buffer, if it is not big enough to hold everything. Converts precision single/double if needed.
