Implementation and performance analysis of pulse pile-up correction algorithm on DSP architecture

This paper describes the method of the Digital pulse processing with a series of algorithms. Digital pulse processing is a signal processing technique in which detector (preamplifier output) signals are directly digitized and processed to extract quantities of interest. Our algorithm is designed for the realization of digitally determining the basic pulse parameters and tackling the problem of pulse pile up in Gamma-Ray spectroscopy. A number of parameter estimation and digital online peak location algorithms are discussed here. A comparison between different techniques of accomplishing the gamma rays is presented. A reference signal from radiation source Cs-137 was acquired by data acquisition system is used in this comparison.
