摘要
本文介绍了利用逆z变换方法得到梯形成形冲击响应函数的推导过程,采用软件产生的单指数信号对其正确性进行了仿真验证。在单指数信号上加载不同标准差的高斯白噪声,经梯形成形仿真得到输出信号和输入白噪声标准差的比值约为0.447。通过搭建数字核信号获取平台,对实际输入核信号进行梯形成形,验证了推导过程与结果的正确性。
In this paper , the derivative process of the trapezoidal shaping impulse response function with the inverse z transform method was introduced , and its correctness was verified when the exponential nuclear signal by software was inputted . When Gaussian w hite noise of different standard deviations and exponential signal are inputted together ,the standard deviation ratio of output signal and Gaussian w hite noise is 0.447 .Finally ,the correctness of the theoretical derivation and result was verified when the actual nuclear signal was trapezoidally shaped which is generated from digital nuclear signal acquisition platform .
