摘要
本文在介绍了等效采样的原理和方法的基础上提出了一种基于EDA技术的实现方案。借助高速发展的EDA技术,可以方便地产生采样信号,大大简化采样触发电路,解决了传统等效采样对复杂周期信号失效的问题,进一步降低对输入信号的要求。并且本方案中A/D变换器处于连续工作状态,改变了传统的连续等效采样每次触发只采集一个数据的模式。
This paper introduces the principle of equivalent-time sampling and brings forth a new method based on EDA. According to the quickly developing technology- EDA, sampling signal can be generated easily and the circuit will be simplified .This system can solve a problem that the traditional method can＇t solve, witch is the equivalent sampling of complex signal. So the restriction to the input signal is released. The AID convertor can work continuously, witch is quite different from the traditional continuous equivalent sampling .
