摘要
文章分析了加速度传感器的信号特点,针对此特点从模拟滤波器入手,采用双线性变换法设计了三种数字滤波器,利用MATLAB中fdatool进行数字滤波器的仿真,三种滤波器均可基本满足指标要求。并采用Visual C++语言进行仿真,得出结论:切比雪夫II型数字滤波器能够比较有效的对加速度传感器的信号进行滤波,这种数字滤波器在实际应用中具有可行性,对于加速度传感器的信号处理有一定参考价值。
In this paper, we firstly analyzed the signal traits of acceleration sensor. According to these traits, then we started with analogy filter, designed three kind of digital filter adopting bilinear transform method, utilized the fdateol of MATLAB to emulate digital filter. The three kinds of filter can almost meet the demand of acceleration signal＇s measure. At last, we use the language of Visual C ＋ ＋ to emulate the system ,at the same time we elicit a conclusion： the digital filter of Chebyshev Ⅱcan effectively filter the signal of acceleration sensor; this type of digital filter is feasible in the application of practice, and it has some applying value in the signal processing of acceleration sensor.
