| 摘 要： | 直接数值频率合成(DDS)是把一系列数字量形式的信号通过D/A转换器转换成模拟量形式的信号合成技术,在通信领域,DDS因具有频率转换时间短、分辨率高、输出相位连续、相位噪声小等优点得到良好的应用。本文从工程应用的角度给出了DDS的verilog HDL设计,重点给出了波形选择、幅值、频率、相位及DAC TLC5615驱动输出等几部分的设计。

| Abstract: | Direct numerical frequency synthesis （DDS） is a technology, which converts digital signal into analog signals through D/A converter. DDS has a wide application in the field of communication, due to a short-time fre- quency conversion, high resolution, continuous output phase, and the advantage of low phase noise. The DDS ver- ilog HDL has been designed from the view of engineering application, with a focus on the waveform, amplitude, frequency, phase and DAC TLC5615 driving output. |
