Abstract :
A functional approach to the concept of pulse shape synthesis is introduced here. This paper reviews some of the mechanisms influencing the process of signal induction, and the solution of the electric field and charge carrier drift phenomena are considered for arbitrary crystal geometries. Then, performing some well-known principles and a set of simple techniques provides an open way to the implementation of pulse shape analysis algorithms.
