系统设计方案 本系统分电压测量和信号产生输出两大部分
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(Direct Digital Frequency Synthesis,简称DDS或DDFS)为核心，经过AT89S52对DDS芯片内部进行控制，使之输出标准 ...

系统设计方案 频率合成技术在现代电子技术中具有重要的地位。在通信、雷达和导航等设备中
频率合成技术在现代电子技术中具有重要的地位。在通信、雷达和导航等设备中，它可以作为干扰信号发生器；在测试设备中，可作为标准信号源，因此频率合成器被人们称为许多电子系统的“心脏”。直接数字频率合成（DDS——Digital Direct Frequency Synthesis）技术是一种全新的频率合成方法，是频率合成技术的一次革命。本文 ...

数值算法/人工智能 a sub-cell WENO reconstruction method
We introduce a sub-cell WENO reconstruction method to evaluate spatial derivatives in the high-order ADER scheme. The basic idea in our reconstruction is to use only r stencils to reconstruct the point-wise values of solutions and spatial derivatives for the 2r-1 th order
ADER scheme in one dimensio ...
