In the digital nuclear spectrum measurement system, the digital shaping algorithm is usually used to process the nuclear pulse signal to improve the energy resolution of the measurement system. In this paper, the algorithm is simulated by the theoretical formula of spike pulse forming, symmetric zero-area trapezoid forming and symmetric zero-area sine forming, and the Mn sample is excited by the KYW2000A X-ray tube, and the nuclear signal is collected by FAST-SDD. The influence of different forming methods on the energy resolution under different peak-time conditions is studied. The results show that under the same parameters, the peak forming has the highest energy resolution and peak area count. When the peaking time and flat-top time increase, the energy resolution of the other two forming methods first increases and then decreases, which is greatly affected by pulse accumulation; With the increase of peak-reaching time and flat-top time, the corresponding characteristic peak area counts of the three forming methods gradually decrease. %K Energy Resolution %K Nuclear Signal %K Trapezoid %K Peak Area %U http://www.oalib.com/paper/6789056
