Techniques of improved signal extraction in scan conversion-based transient digitizers

The paper deals with a technique to improve the signal extraction from the target of scan conversion-based transient digitizers. At first, the statistical parameters of the digitized charge distribution on each target column are analyzed. Then the statistical parameter trend across the target is evaluated. Finally, the identification of the distribution charge model allows the signal extraction to be improved. Experimental results of tests carried out on an actual scan converter using dc and sinewave signals showed that signal extraction can be improved mostly by correcting the center displacement of the column distributions
