Performance enhancement of scan converter-based transient digitizers by digital image processing

A method for the enhancement of the dynamic performance of scan converter-based transient digitizers is proposed. Firstly, a characterization technique capable of discriminating the best diode target area and so suggesting to the user the best time window set up for the acquisition is illustrated. Then, by considering the charge intensity distribution as a digital image, in the case of signals acquired with missing portions, a two-dimensional filtering algorithm capable of restoring the signal is shown. Experimental results obtained by the proposed method on an actual transient digitizer are also reported
