摘要
介绍了基于MAX275的有源带通滤波器组的设计方法,阐述了该芯片在某声脉冲系统中的应用以及该系统的结构和功能组成。通过MATLAB仿真以及试验表明,该滤波器有效地抑制了噪声和干扰,保障了系统的正常工作。
The designing method based on the chip MAX275 is introduced. The key points of the application of the chip in the system using the acoustic impulse are explained in details The configuration composition is presented. The Matlab simulating results show that because the noise and disturbance can be restrained effectively by the filter, the system can work well.
