摘　　要：以伪均匀随机数为基础,根据大数中心极限定理,产生高斯分布随机数。以89C51单片计算机系统为硬件,12位D/A转换器为输出,实现了输出脉冲幅度高斯分布,输出脉冲时间间隔可以是周期性的,也可以是指数分布的。该随机信号发生器可以实现高精度高斯分布的输出控制,较好地仿真了核脉冲幅度和时间的随机特性。Based on pseudo random uniformity number and the central limit theory of great numeral, random numbers of Gaussian distribution are produced. By adopting the single chip computer of 89C51 as hardware and 12-bit D/A converter as output, Gaussian distribution of output pulse amplitude was implemented. The time duration of output pulses could be in both exponential distribution and periodic distribution. The random signal generator has achieved output control of highly precise Gaussian distribution, and imitated random characteristic of nuclear pulse in amplitude and time.
