An enhanced version of an algorithm developed by Maguire and Marshall in their computerized DLTS system is presented. Improvements consist of introducing analysis of partial processing of digitized transients by deleting the initial part, which usually includes the loading transient caused by the measurement circuit RC constant. Also, a method to calculate trap concentration without using correlation functions is added. Some of the limitations involved with the use of this algorithm are also discussed
