中文摘要:
      水声引信要求滤波器必须有较低的功耗和较快的阻带衰减。基于高性能开关电容滤波器LMF100设计一种适于水声引信的带通滤波器。采用了两种设计带通滤波器的方法,通过实际测试对两种方法作了比较,最终设计出了过渡带窄、截止频率精确可调、阻带衰减快、低功耗的带通滤波器,并给出了实际调试的结果。
英文摘要:
      Filter in underwater acoustic fuze must be low power-consuming and fast decreasing in stop-band.A bandpass filter fit for underwater acoustic fuze is designed by using high performance dual switched capacitor filter LMF100.Two methods of designing the band-pass filter are used and compared by testing.Finally a band-pass filter with narrow transition band,accurately controllable cutoff frequency,great attenuation in stopband and low power consumption is successfully developed,and the debugging result of the developed circuit is given.
