| 中文摘要 | 介绍了用于多道脉冲幅度分析的数字基线估计方法的基本特点,利用泛函变分方法推导了最小噪声基线滤波器的计权函数,利用Fourier变换导出了数字基线估计的频率响应,探讨了参数取值对其幅频特性的影响。还利用MATLAB模拟了电荷灵敏前置放大器输出的噪声电压信号,验证了最小噪声数字基线估计的处理效果。研究结果表明,数字基线估计方法能实现最佳基线估计,特别适于在数字化多道脉冲幅度分析中使用。; The basic features of digital baseline estimation for multi-channel pulse height analysis are introduced. The weight-function of minimum-noise baseline filter is deduced with functional variational calculus. The frequency response of this filter is also deduced with Fourier thansformation, and the in fluence of parameters on amplitude frequency response characteristics is discussed. With MATLAB software,the noise voltage signal from the charge sensitive preamplifier is simulated, and the process ing effect of minimum-noise digital baseline estimation is verified. According to the results of this re search, digital baseline estimation method can estimate baseline optimally, and it is very suitable to be used in digital multi-channel pulse height analysis. |
