A PC SPECTROSCOPY LINE SIMULATION TO VALIDATE NEW DIGITAL FILTERING ALGORITHMS

A new digital algorithm called the Conditional Polynomial Filter (CPF) is presented to solve the problem of the separation of radiation puls es from electronic noise of the same level. A PC-based simulation of a practical very low signal-to-noise measurement case is presented, whi ch proves the interest of this new algorithm vs. the classical analog signal processing done by a shaper: on the CPF signal the vanishing of the gaussian noise which is present on the shaper signal was observed . The simulation results were followed by successful real experiments. This validation process demonstrates also the interest of a PC simula tion for the early phases of a new measurement algorithm development.
