一种新型教学系统的设计——信号发生与存储示波器

A new-style teaching system design——a signal generator and storage oscillograph

介绍了基于ADuC848的新型教学系统的设计——信号发生与存储示波器。系统实现了低频信号的数字存储示波、标准生理信号、用户自定义信号的产生和显示。该系统采用美国AD公司新推出的一款高性能微处理器ADuC848作为控制核心，并配置液晶显示屏和非易失性存储器。它具有硬件电路设计简单、人机对话界面友好和成本低的特点，而且输出波形稳定性好、质量高，因此对医学与医学仪器及其相关领域的教学和科研有较高的实际应用价值。

A new -style teaching system design-a signal generator and storage oscillograph is presented in the paper. It integrates powerful functions into the system： digital storage oscillograph for displaying low - frequency signal and signal generator for outputting standard signals as well as user defining signals. It adopts a new high performance microconverter ADuC848 released by the ADI as the control core in the system, configuring a liquid crystal module and Flash/EE memory. It has the advantage of simple hardware circuit design, facility man - machine conversation interface, nonvolatile storage, convenient operation with low price. In addition, it can produce stability and high quality waveform. So it has high practical value in the teaching and researching of the medicine ＆ medical instrumentation.
