Design of Digital FIR (Finite impulse Response) Filters for Nuclear Pulse Processing using Convolution Method

摘要

In this paper, analytical expressions are derived for digital filters using convolution functions, which converts a typical pulse from NaI (TI) crystal+PM tube detector assembly into trapezoidal, truncated cusp and Gaussian shaped pulses. This is basically a FIR (finite Impulse response) filter. These analytical expressions give good insight into the parameters on which the convolution function depends.
