Abstract :
A method for the design as well as implementation of FPGA-based Direct digital synthesizer (DDS) is firstly presented in this paper. And then corresponding system simulation and experimental results are given. The DDS for generating a sinusoidal signal owns the features of simple circuit, easy to be controlled, stable performance, high frequency conversion speed and fine accuracy etc. And its output frequency falls in the range of 0Hz ~160KHz with 5 Hz of steps.
