摘　　要：利用EPLD器件模拟了n维贝努里试验,通过改变其参数,得到符合二项分布、泊松分布以及高斯分布的随机脉冲。当信号满足泊松分布时,脉冲平均计数率可达100kHz,最小时间间隔为100ns。对电路分别作了一定时间内脉冲计数统计分布检验和脉冲时间间隔分布检验,证明在时间特性上可用于仿真一般核信号源。Using a piece of EPLD's device to simulate the Bernoulli trial, we can get the random pulse subjected to binomial distribution. If we change the parameters of binomial distribution, the random pulse subjected to the Poisson distribution and the Gauss distribution will be generated. When statistical character of random pulse subjects to Poisson distribution, the maximal mean rate ( average frequency) could be up to 100 kHz, and the minimal interval of two random pulses is 100ns at last, the tests on two aspects are made: the first tests the statistical distribution of pulse counts in a given time, and the other tests the statistical distribution of the time interval of random pulses.
