Abstract: The invention provides a method for removing noise spikes from an electrical input signal having an AC component, comprising the steps of determining the actual rms value of the input signal, low pass filtering the input signal, producing a variable offset, said variable offset being a function of the actual rms value, forming a variable threshold by superimposing the variable offset to the low pass filtered signal, comparing the input signal to the variable threshold, creating a spike detection signal when the input signal passes the variable threshold, and blanking the input signal during the occurrence of the spike detection signal.

Abstract translation: 本发明提供了一种从具有AC分量的电输入信号中消除噪声尖峰的方法，包括以下步骤：确定输入信号的实际均方根值，对输入信号进行低通滤波，产生可变偏移，所述可变偏移量为 实际均方根值的函数，通过将可变偏移叠加到低通滤波信号形成可变阈值，将输入信号与可变阈值进行比较，当输入信号通过可变阈值时产生尖峰检测信号，并消隐输入 在发出尖峰检测信号时发出信号。
