一、引言峰值保持器是一种特殊的采样——保持电路,要求输出信号自动跟踪输入信号的峰值,并保持该峰值。峰值检波器可以用来分析瞬变波形和周期波形,在气体色谱分析和质谱分析中都有应用;在磁测量中测量幅值磁化曲线时也要分别
I. Introduction The peak keeper is a special kind of sample-and-hold circuit that requires the output signal to automatically track the peak value of the input signal and maintain that peak. Peak detectors can be used to analyze both transient and periodic waveforms, both in gas chromatographic and mass spectrometry applications; when measuring amplitude magnetization curves in magnetic measurements separately
