摘　　要：为了快速而精确实现所需八阶带通模拟滤波器的设计,保证水声信号接收机系统的滤波与增益性能,文章提出了基于Maxim公司的滤波器设计芯片MAX274快速实现八阶Butterworth带通模拟滤波器的设计方案。结合水声信号接收机系统的指标,设置滤波器设计软件的设计参数,并通过Multisim仿真得到带通滤波器频率响应曲线进行对比验证,其滤波与增益性能在相应频带内效果好。体积小、单片集成、方便调试的优点,使其更加适合该系统滤波器的设计。In order to achieve required eighth-order bandpass analog filter design fast and accurately, to ensure the performance of filtering and gain of underwater acoustic signal receiver system, a design that implementing eighth-order band-pass analog filter quickly is proposed in this paper which is based on the MAX274 chip of Maxim. Combined with the index of underwater acoustic signal receiver system, the filter design software parameters are setted, bandpass filter frequency response curve is obtained and verified by Multisim simulation, it’s observed that the bandpass filter’s filtering and gain performance in the corresponding frequency band is fine. The advantages of small size, monolithic integration and convenient debugging, make the MAX274 chip more suitable for the filter design of the system.
