A. method: it is equal to ” amplitude limiting filter method” + ” eliminate shake filter method ” amplitude limiting first and eliminating shake after

B. advantages: inherit “limiting” and “Xiao shook” the advantages of improved “eliminating mechanically dithered filter method” certain deficiencies, avoiding interference into the system.

C. disadvantages: it is not suitable for quick change parameters.

D. test code

int Filter_Value; 
int Value; 
  
void setup () {
   Serial.begin (9600); / / initialize the serial communication 
   randomSeed (analogRead (0)); / / random seed 
   Value = 300; 
} 
  
void loop () {
   Filter_Value = Filter (); / / get the filter output value 
   Serial.println (Filter_Value); / / serial output 
   delay (50); 
} 
  
/ / Used to randomly generate a current value of around 300 
int Get_AD () {
   return random (295, 305); 
} 
  
/ / Debounce filtering 
# define FILTER_N 12 
int i = 0; 
int Filter () {
   int new_value; 
   new_value = Get_AD (); 
   if (Value! = new_value) {
     i + +; 
     if (i> FILTER_N) {
       i = 0; 
       Value = new_value;
