摘要
在工业生产和科学研究中，对浮动信号的自动跟踪与检测是经常遇到的一个问题。本文给出一种新的信号跟踪与检测电路，它不但可以在直流电平或缓慢浮动的电平下检测到脉冲信号，在浮动电平变化速度较快（如１ｋＨｚ）的情况下，也能准确地检测出脉冲信号。
Automatic tracking and detecting on floating signals are the commonly used method in indeustrial productions and scientific research. A new tracking and detecting circuit is given in the paper. With this circuit the pulse signals could be detected on DC level of slowly floating level. Pulse signals can also be detected on faster changing floating level (e. g. 1khz).
