摘　　要：将S-K滤波器应用于核脉冲信号的成形中,采用较少的级数就可以达到准高斯波形的输出.仿真了基于低通S-K滤波器的滤波成形电路的特性,并给出了最佳的滤波器参数.采用宽带高速运算放大器设计和实现了该电路,通过实验证明了该电路的优越性.Sallen-Key filter was used in shaping of nuclear pulses and, with few stages of filters it was possible to reach the Gaussian waveform output. The characteristics of the shaped circuit base in Sallen-Key low pass filter were simulated and the optimal parameters of this filter were given. This circuit was designed and realized by using a broad-band op-amplifier and the experiment testified the advantage of the circuit.
