10种软件滤波程序

1、限副滤波#defineA10charvalue;charfilter(){charnew_value;new_value=get_ad();if((new_value-value>A)||(value-new_value>A)returnvalue;returnnew_value;}

2、中溴腻男替位值滤波法#defineN11charfilter(){charvalue_buf[N];charcount,i,j,temp;for(count=0;count<N;count++){value_buf[count]=get_ad();delay();}for(j=0;j<N-1;j++){for(i=0;i<N-j;i++){if(value_buf[i]>value_buf[i+1]){temp=value_buf[i];value_buf[i]=value_buf[i+1];value_buf[i+1]=temp;}}}returnvalue_buf[(N-1)/2];}

3、算术平均滤波法#defineN12charfilter(){intsum=0;for(count=0;count<N;count++){sum+=get_ad();delay();}return(char)(sum/N);}

4、递推平均滤波法（又称滑动平均滤波法）#defineN12charvalue_buf[N];chari=0;charfilter(){charcount;intsum=0;value_buf[i++]=get_ad();if(i==N)i=0;for(count=0;count<N,count++)sum=value_buf[count];return(char)(sum/N);}

5、中位值平拨揞搠床均滤波法（又称防脉冲干扰平均滤波法）#defineN12charfilter(){charcount,i,j;charvalue_buf[N];intsum=0;for(count=0;count<N;count++){value_buf[count]=get_ad();delay();}for(j=0;j<N-1;j++){for(i=0;i<N-j;i++){if(value_buf[i]>value_buf[i+1]){temp=value_buf[i];value_buf[i]=value_buf[i+1];value_buf[i+1]=temp;}}}for(count=1;count<N-1;count++)sum+=value[count];return(char)(sum/(N-2));}

6、限幅平均滤波法略参考子程序1、3

7、一阶滞后滤波法#definea50charvalue;charfilter(){charnew_value;new_value=get_ad();return(100-a)*value+a*new_value;}

8、加权递推平均滤淡捋墨热波法#defineN12charcodecoe[N]={1,2,3,4,5,6,7,8,9,10,11,12};charcodesum_coe=1+2+3+4+5+6+7+8+9+10+11+12;charfilter(){charcount;charvalue_buf[N];intsum=0;for(count=0,count<N;count++){value_buf[count]=get_ad();delay();}for(count=0,count<N;count++)sum+=value_buf[count]*coe[count];return(char)(sum/sum_coe);}

9、消抖滤波法#defineN12charfilter(){charcount=0;charnew_value;new_value=get_ad();while(value!=new_value);{count++;if(count>=N)returnnew_value;delay();new_value=get_ad();}returnvalue;}
