摘要
设计了一套核辐射信号数字仿真发生器,可以近似数字核仪器系统中的探测器-前置放大器、前端条件线路、高速模/数变换等部分。利用这套仿真发生器,只需一台PC机就可以进行数字处理算法的开发,减少了对硬件设备的需求,降低了数字核仪器系统的研发成本,增强了数字处理算法开发的灵活性。通过仿真信号能谱测量与实际采样信号能谱测量的对比,验证了核辐射信号数字仿真发生器的有效性和实用性。
A digital simulative generator for the nuclear radiation signal has been designed, which is provided with the function close to that of the subsystem with a detector-preamplifier, a front-end condi- tioner and a high speed ADC in digital nuclear instrument system. Developing digital processing algorithm only need a person computer（PC）with designed digital simulative generator,which can both reduce the cost and enhance the flexibility in developing digital nuclear instrument system. The energy spectra for the simulation signal and the real sampling signal are measured. The results show that the designed digital simulative generator for the nuclear radiation signal is reliable and useable.
