Description: 1 用WL00算法速度比EL99快，这里实现的是单分辨率的算法,WL00算法好象不适合结构性强的纹理的合成
2.用WL00算法合成纹理，使用多分辨率金字塔改善合成效果,但是没有用TVSQ加速算法-WL00 algorithm with a speed faster than the EL99, here is the realization of the single-resolution algorithm, WL00 algorithm does not seem to fit the strong structural texture synthesis 2. WL00 algorithm using synthetic texture, the use of multi-resolution pyramid improve synthesis results, but did not accelerate the algorithm used TVSQ Platform: |

通用信号源设计方法。给出了系统主要硬件电路的实现 ,并利用汇编语言开发了主控软件。实验结果表明 ,硬件电路结构
简单 ,软件控制灵活 ,软件和硬件拓展性好 ,输出信号频率稳定 ,分辨率高。-Direct Digital Frequency Synthesis (DDS) is a new technology in the field of f requency synthesis. Making use of
the integrated DDS chip can satisfy the requirement s of designing a high performance signal generator . In this article ,the prin2
ciple and function features of Direct Digital Synthesizer AD9951 is int roduced and a method to design a general signal generator
centered on AD9951 ,using a single chip to cont rol is proposed. The significant part of hardware circuit of the system is illus2
t rated and the main sof tware is developed in compiling programming language to cont rol the chip AD9951. Experiment result s
indicate that the hardware circuit const ruction is plain and the programming is flexible ,besides ,the hardware and sof tware are
both easily extended. Furthermore ,the output signal is stable and has high f requency resolution. Platform: |
