Designation and Implementation of High Frequency Signal Generator Based on DDS
WU Jin-ying · Journal of Fujian Normal University · 2010
Direct digital synthesis (DDS) is widely used in the field of wireless communication.With FPGA, the design and implementation of signal modulator based on DDS is introduced.This system is mainly controlled by EP2C35 of Altera, which fundamental frequency is adjustable, between 1 kHz and 70 MHz.The system features small volume, well stability, high step precision and output waveform undistorted.
