| 摘 要： | 将混沌理论应用于数字示波器的触发电路设计中,并用嵌入式系统实现.有利于捕获到微弱信号的微弱变化(可达10-6V),并将它作为触发点控制信号的采集,极大地提高了观测信号的性能和质量,测量精度高,特别适用于观测在长时间内变化非常缓慢但又有很微弱的变化的信号.且利用了嵌入系统的优点,简化了电路的设计,灵活方便,为数字示波器触发电路设计提供了一种新的思路. |
| 关 键 词： | 嵌入式系统 混沌 数字示波器 触发 微弱信号 |

| Abstract: | Applying chaotic theory to trigging circuit os digital oscilloscope(DSO),it could measure weak signal and capture the point when the weak signal changed very small amplitude.Using it as trigger point to control sampling and display,it got good quality and convenience to observe the signal,especially for observing the signal changing very slow during a very long time but having a very weak changing.because it could measured 1nv and got high precision by chaotic measurement model.Also realized chaotic measurement with the embedded system,it simplified the design of circuit.This provides a new way for design of oscilloscope. |
| Keywords: | embedded system chaos digital oscilloscope trigging weak signal |
