摘要
随着数字信号处理技术的发展,DDS技术被越来越广泛的应用于各种数字系统中,它是一种基于数字电路的频率合成方法,随着各种大规模数字可编程芯片的出现,使用DDS有效地解决了模拟电路频率合成技术对相位和频率控制的复杂性和误差较大的特性。首先介绍了DDS技术的基本工作原理和结构,然后用Verilog硬件编程语言实现了基于DDS的信号发生,在此基础上设计了一种基于DDS技术的多路线性调频信号,并给出了其仿真结果,验证了其正确性。
With the development of digital signal processing technology, DDS technology is more widely used in various digital systems, which is based on the frequency of the digital circuit synthesis method, with a variety of large-scale digital programmable chips appear, effectively solved with DDS analog frequency synthesis phase and frequency control of the complexity and characteristics of a large error. DDS technology first introduced the basic working principle and structure, and then use the Verilog hardware programming language to implement the DDS-based signal generation, on the basis of the design of a DDS-based muhi-channel linear FM signal, and gives the simulation the results verify its correctness.
