Design of the Rectangular Band-pass Filter

为了提高舰炮无线电引信抗海浪杂波和干扰机干扰的性能 ,分析了它们的干扰机理 ;设计了一种频率特性近似矩形的带通滤波器 ;并对所设计的电路进行了仿真 ;结果表明 ,该电路可以实现上。

In order to improve the anti jamming performance of radio fuzes for the chase gun, based on the jamming mechanism of the wave of sea and the jammer, this article designs a rectangular band pass filter and gives the computer simulated result. The result shows that the designed circuit can recognize the high cut off frequency and low cut off frequency of the Doppler frequency.
