10种软件滤波方法的示例程序

1、限副滤波

/* A值可根据实际情况调整

value为有效值，new_value为当前采样值

滤波程序返回有效的实际值 */

#define A 10



char value



char filter()

{

char new_value

new_value = get_ad()

if ( ( new_value - value > A ) || ( value - new_value > A )

return value

return new_value



}



2、中位值滤波法

/* N值可根据实际情况调整

排序采用冒泡法*/-10 kinds of software filtering method one example of the procedure, limit the Deputy filter/* A value can be adjusted according to the actual value for the RMS, new_value filter for the current sampling procedures for the effective return of the actual value* /# define A 10 char value　char filter () (char new_value　new_value = get_ad ()　if ((new_value- value>　A) | | (value- new_value>　A) return value　return new_value ) 2, the median filtering method/* N values can be adjust the actual situation in the use of bubble sort method* /
