C#实现消抖滤波算法 输入List<double>返回List<double>

消抖滤波算法可以用于去除输入信号中的噪声。具体实现如下：

using System;
using System.Collections.Generic;

public class DebounceFilter
{
    private List<double> inputSignal;
    private double threshold;
    
    public DebounceFilter(List<double> inputSignal, double threshold)
    {
        this.inputSignal = inputSignal;
        this.threshold = threshold;
    }
    
    public List<double> ApplyFilter()
    {
        List<double> outputSignal = new List<double>();
        
        for (int i = 0; i < inputSignal.Count; i++)
        {
            double currentValue = inputSignal[i];
            
            if (i == 0 || Math.Abs(currentValue - outputSignal[outputSignal.Count - 1]) > threshold)
            {
                outputSignal.Add(currentValue);
            }
        }
        
        return outputSignal;
    }
}

使用示例：

List<double> inputSignal = new List<double> { 1.2, 1.3, 1.5, 1.9, 2.1, 1.8, 0.9 };
double threshold = 0.5;

DebounceFilter filter = new DebounceFilter(inputSignal, threshold);
List<double> outputSignal = filter.ApplyFilter();

foreach (double value in outputSignal)
{
    Console.WriteLine(value);
}
