The design of sinusoidal signal generator on FPGA

This article is meant to introduce the sine-wave generator based on the programmable logical component FPGA and direct digital frequency synthesis(DDS),consisting of modules of frequency control,phase control,digital-analog conversion,and sine-wave generation,all of which are realized in FPGA by means of VHDL language program and found to be up to the design requirement through software simulation and hardware testing.
