摘要

从RC高低通滤波电路输入输出电压之间的线性常系数微分方程出发，推导出数字化CR高通和RC低通滤波器的系统传递函数，进而推导出数字化CR-RC

滤波器的频域特征和时域成形特征进行分析和测试，并通过实验，对数字化CR-RC

成形滤波器滤波成形前后不同脉冲信号的能谱及能谱全能峰能量分辨率进行了测试。实验结果表明，该滤波器可对数字化的核信号成形成高斯型，使脉冲信号的上升沿变缓，峰顶变得更加平坦，提高信噪比，进而提高系统能量分辨率。

Abstract

Backgrounds

The CR-RC

filter is a classic and widely used filter for nuclear analog signal processing circuit. It possesses the advantages of superior performance and simple implementation.

Purpose

This study aims to digitize CR-RC

filter and discuss its performance with different RC and

parameters.

Methods

Based on the linear differential equation with constant coefficients of analog RC (CR) filter's input and output voltage

recursive formulas of the digitized CR high-pass filter and RC low-pass filter were derived

and system transfer function of digitalization CR-RC

filter was further deduced. After analysis of the characteristics of digitalized CR-RC

filter in time-domain and frequency-domain

both the energy spectra and the resolution of full energy peak before and after the CR-RC

filter were experimental tested.

Results

The digitalized nuclear pulse signal was shaped as Gaussian waveform by CR-RC

filter. The energy resolution of

137

Cs spectrum was improved 1% through CR-RC

filter and could further enhanced by adjusting RC and

parameters.

Conclusion

Digitalization CR-RC

filter could be used to reform pulse signal to increase the signal-to-noise (SNR)

hence improve spectrum resolution of nuclear signal.
