Abstract :
This paper deals with a method for the dynamic characterization of scan conversion-based transient digitizers. Such a method is based on the application to the digitized data of a two-dimensional filtering process, implemented by using the Walsh transform. The filtering process avoids incorrect evaluation of the digitizer dynamic performance. In order to test the proposed method, a scan converter model has been also developed. The validity and the application range of the method are illustrated through numerical and experimental results
