摘要
本文阐述一种随机信号过载检测器的原理和电路结构,它兼有既能识别过载又能实现信号灵敏可靠检测的功能。并介绍采用单片微机实现测量系统实时采集数据的方法.它虽是针对具体的测量系统而设计的,但对随机信号的电子测量有普遍适用的意义.
The paper describes the circuit principle and the construction of a overload detector which has functions of discriminating overload signal and detecting valid signal for a random acoustic pulse. And a method of real-time data acquisition for a measurement system by using single chip computer is also proposed. The detector and the method are designed for a special acoustic measurement system, but they can be used generally in electronic measurement of random pulse signal.
