STM32处理器的参数可变FIR数字滤波器设计

针对数字滤波器适用范围的问题,提出了一种无线非接触、滤波参数可变的数字滤波器.通过LabVIEW软件与路由器无线通信,路由器与ESP8266WIFI模块无线通信,ESP8266WIFI模块与STM32模块串口通信实现滤波参数无线非接触更改最后实验证明了设计的有效性.

Variable Parameters FIR Digital Filter Design Based on STM32

In order to solve the applicability problem of the digital filters,a kind of digital filter is proposed,which is wireless non-contact and changeable filter parameter.The filter communicates with the router using LabVIEW software,and the router communicates with the ESP8266WIFI module.The ESP8266WIFI module communicates with the STM32 module serial port to implement the filter parameter wireless non-contact change.Finally,the test results verify the accuracy of the design.
