摘 要
本系统的设计综合了EDA技术和单片机技术的二者之所长，实现了二者在性能、功能以及资源上的良好结合，整个系统可简略分为波形产生模块、单片机控制模块、LCD显示、键盘、幅度控制模块等功能模块。采用直接数字频率合成（DDFS）技术，通过软件对其波形进行控制，实现多种波形的输出及组合。该系统可实现的频率范围宽、幅度和频率精度高，并且实现电路简单，结构较优，利用液晶显示屏实现了良好的中文人机交互界面。 Abstract :The design of this system synthesized the advantages of EDA technology and Microcontroller technology ,and it ……The whole system is made up of the part of wave producer ,the controller of microcontroller ,the display part of LCD ,the keyboard and the controller of range and frequency .The system adopts 东方神起 stillthe四种形态和教育惩处相结合 method of Direct Digital Frequency Synthesis (DDFS) , whose wave is controlled through software .A few kinds of waves and their combinations can be produced .We can get wide and accurate frequency and high range .At the same time ,this system has less sample circuit and bett
pubmeder structure .The LCD that we used can provide us very clear menu when we communicate with the machine.
