Synthesis of optimal digital shapers with arbitrary noise using simulated annealing

This paper presents the structure, design and implementation of a new way of determining the optimal shaping in time-domain for spectrometers by means of simulated annealing. The proposed algorithm is able to adjust automatically and in real-time the coefficients for shaping an input signal. A practical prototype was designed, implemented and tested on a PowerPC 405 embedded in a Field Programmable Gate Array (FPGA). Lastly, its performance and capabilities were measured using simulations and a neutron monitor.
