摘　　要：介绍了一种新型电子隧道加速度计的工作原理 ,详细分析了该加速度计输出信号的有效成分及噪声与干扰 ,设计了利用LabVIEW虚拟仪器开发平台的信号分析与处理程序。基于对电子隧道输出信号的分析 ,仿真了相应的模拟信号 ,并且通过对该模拟信号的软件处理 ,抑制了噪声 ,消除了工频干扰 ,将被噪声淹没的有效成分提取出来 ,从而证明了该方法的有效性。The principle of a new electronic tunneling accelerator is introduced and the desired component, the noise and the disturbance of the sensor's output signals are analyzed in detail. With the LabVIEW virtual instrument development platform, the method of signal analysis and processing is designed. Based on the analysis of the output signals of the electronic tunneling, the related simulative signals have been simulated and processed,thus restraining the noise and deleting the power frequency disturbance. Finally the desired component concealed by the noise has been obtained.
