Abstract：The fundamental principle for the direct digital frequency synthesis is introduced in brief, especially, the realization in hardware for the direct digital frequency synthesis based on FPGA（field programmable gate array）is presented. The experiment indicates that the direct digital frequency synthesis based on FPGA can generate any kind of waveform and the frequency, phase and amplitude can be adjusted arbitrarily.
