本系统分电压测量和信号产生输出两大部分，电压测量部分以模拟电路为主，配合放大模块、A/D转化模块、显示模块；通过凌阳单片机进行数据处理，在误差允许范围内显示测量电压值。信号产生以直接数字式频率合成器为核心，经过AT89S52对DDS芯片内部进行控制，使之输出标准正弦波形，利用编程实现频率预置、步进，达到电压输出频率的可调节步进。通过调试与测量完成了题目的基本部分和全部发挥部分的要求并有自己的创新。-Voltage measurement points of the system and the output of two major signals, voltage measurement circuitry to simulate the main part, with the amplification module, A/D conversion module, display module through Sunplus Single-chip data processing, in the range of error allowed shows the value of measuring voltage. Signal generated by direct digital frequency synthesizer for the core of the DDS chip AT89S52 after the internal control standards so that the output sine wave shape, frequency of use of pre-programming, step to the output voltage adjustable frequency step. Debugging and measurement, through the completion of the basic part of the topic and all the requirements to play a part and have their own innovation.
