摘要
介绍一种可编程Butterworth滤波器设计。针对超声波回波信号波形处理的要求 ,设计多通道Butter worth滤波器 ,通过对高性能电子开关编程控制选择相应滤波器 ,实现对滤波器通带宽度变换。这种滤波方法也可以应用于其他信息采集处理。
An effective method is proposed for the design of programmable butterworth filter.According to the need for ultrasonic echo signal processing,we design multichannel butterworth filter and control analog switches to select different filter by program,to achieve bandpass transform.The filter technology can also be applied to others data acquisition.
