The Design of Direct Digital Frequency Synthesizer Based on FPGA

摘要：

The design and implementation of DDS (digital frequency synthesizer) based on FPGA are introduced in this article. The DDS is a new digital frequency synthesis technique based on fhe concept of phase, it has many advantages such as short frequency switch time and high resolution etc. The simulation results are consistent with the theoretical analysis and finally a steady and high precision signal sine wave is gained.
