在核子和等离子体物理实验、原子工程以及火箭技术中经常要对毫微秒的脉冲进行峰值检出,并经模数转换器送给计算机进行数据处理。脉冲峰值的检出经常采用比较法和保持法。我们曾在1974年采用放电法做成一台高速脉冲峰值数字电压表,达到如下指标:动态范围0.4～0.5伏,精度≤1%,当脉冲幅度为2.5伏时其响应时间为16毫微秒。和当时的世界水平相近。1978年我们为了配合等离子体物理实验,把1974年的运算放大 In nuclear and plasma physics experiments, atomic engineering and rocket technology, it is often necessary to detect the peak of a nanosecond pulse and send it to a computer for data processing through an analog to digital converter. Pulse peak detection often used comparison and retention method. We used a discharge method in 1974 to produce a high-speed pulse peak digital voltmeter that achieved the following specifications: dynamic range of 0.4 to 0.5 volt with accuracy of 1% or less, 16 ns response time at 2.5 volt pulse width . Similar to the world level at the time. In 1978 we cooperate with the plasma physics experiment, the operation of 1974 magnified
