Design and Implementation of Direct Digital Frequency Synthesis Sine Wave Generator Based on FPGA
Zheng Xiaolin · Journal of Electron Devices · 2005
Based on FPGA and D/A chip, a sine wave generator that frequency and phase is controllable is designed with direct digital frequency synthesis (DDS) technology. The principle and structure of DDS is expounded, and also the design thinking and implementation method. The output wave by test achieves the required aims, easy control and high performence. It is proved that the design based on FPGA with DDS is dependable and feasible.
