[OS program] clk DL : 0: 现代电子系统课程设计基于DDS技术利用VHDL设计并制作一个数字式移相信号发生器。（1）基本要求： a．频率范围：1Hz～4kHz，频率步进为1Hz，输出频率可预置。 b．A、B两路正弦信号输出，10位输出数据宽度 c．相位差范围为0～359°，步进为1.4°，相位差值可预置。 d．数字显示预置的频率（10进制）、相位差值。（2）发挥部分 a．修改设计，增加幅度控制电路（如可以用一乘法器控制输出幅度）。 b．输出幅度峰峰值0.1～3.0V，步距0.1V，显示预置值。 -Modern electronic system design is based on DDS technology courses use VHDL to design and produce a digital shift Signal Generator. (1) the basic requirements: a. Frequency range: 1Hz ~ 4kHz, frequency step for the 1Hz, output frequency can be preset. b. A, B two sinusoidal signal output, 10-bit output data width c. Phase difference range of 0 ~ 359 °, stepping to 1.4 °, the phase difference value can be preset. d. Figures show that the frequency of Preferences (10 M), phase difference value. (2) to play a part of a. Modify the design to increase the rate of control circuit (for example, could use a multiplier to control the output rate). b. Peak-to-peak output rate of 0.1 ~ 3.0V, step 0.1V, show preset value.

[OS program] ddssdfd DL : 0: 以把直接数字频率合成（DDS）看成这样一种技术，它能用数字值形式的信号控制正弦波的频率。最简单的DDS电路包括一个二进制计数器，一个以等间隔正弦波值进行全波编程的ROM，以及一个数模转换器，用于将存储的正弦波值转换为但这种结构并不灵活。 -To the Direct Digital Synthesis (DDS) as such a technology, it can use the digital value of the form of the frequency of sine wave signal control. The simplest DDS circuit includes a binary counter, such as between a full-wave sine wave value programmed ROM, and a Digital to Analog, used to store the value of the sine wave is converted to such a structure but is not flexible.
