中文摘要：
利用前置放大电路、单片机ATMEGA16以及集成芯片MAX262等电路,设计了一种振动信号调理系统并实验验证了其可行性。由编制的VC软件界面输入滤波器中心频率和其他参数,通过计算机向单片机发出指令,控制滤波芯片MAX262进行信号滤波,消除噪声。实验证明,所设计的振动信号调理电路简便可行,信号检测效果良好。
英文摘要：
A signal processing electric circuit used in vibration signals processing system has been designed,which contains the pre-amplifier,the single chip ATMEGA16 and the microprocessor programmable MAX262 and so on.Its feasibility test is carried out.The center frequency and other parameters are input into the computer by VC software programmed,and the computer sends these instructions to the single chip.The single chip controls MAX262 filter to work regularly and the noise signals are well filtered.The experimental results show that the designed signal processing electric circuit is feasible and its effect of application is good.
