【Abstract】 Nuclear pulse shape pile-up and its traditional processing circuit are analyzed in detail.A scheme of pulse shape discrimination system based on DSP and high-speed A/D converter techniques are presented.Besides rejecting pulse pile-up and implementing pulse height measurement effectively,it also reduces the system dead time and simplify the design of analog circuit.On the basis of this system,it is easily to construct a digital measurement instrument such as single-channel and multi-channel analyzer.更多还原
