1、限幅滤波法（又称程序判断滤波法）
A、方法：
根据经验判断，确定两次采样允许的最大偏差值（设为A）
每次检测到新值时判断：
如果本次值与上次值之差<=A,则本次值有效
如果本次值与上次值之差>A,则本次值无效,放弃本次值,用上次值代替本次值
B、优点：
能有效克服因偶然因素引起的脉冲干扰
C、缺点
无法抑制那种周期性的干扰
平滑度差
-1, limiting filtering method (also known as programs to gauge the filtering method) A, Method: based on experience and determined that the maximum allowable deviation of the two sample values (Set A) to a new value for each test to determine: If this value is the difference between the previous value of < = A, then this value is valid if the second value is the difference with the previous value of> A, then this value is not valid, abandon the present value, using the last value instead of the present value of B, advantages: causal factors can effectively overcome the interference caused by pulse C, shortcomings can not suppress the interference of the kind of smoothness of periodic difference
