基于Verilog HDL的DDS信号发生器设计
Design of DDS Signal Generator Based on Verilog HDL
摘要
Abstract
In order to meet the demands for high-performance signal sources in fields such as infrared communication and radar detection,a design method of an adjustable signal generator is introduced.By adopting the direct digital frequency synthesis(DDS)technology and counter synthesis algorithm,four waveform signals of square wave,triangular wave,sawtooth wave and cosine wave are respectively output in a single channel.Meanwhile,through different keys,the functions such as frequency,initial phase,amplitude adjustment and waveform selection of the four waveforms can be realized.This paper analyzes the de-sign principle of DDS and models the signal generator,uses Verilog HDL language to design the DDS signal generator.The functional simulation is carried out through Modelsim.The simulation results show that the designed DDS signal generator can achieve the expected effect and has certain practical significance and practicability.关键词
