?The complex warble tone is converted to the pure tone to simplify it,the pure tone is digital prossesed by the use of DDS technology in the base of technology,the discrete amplitude of the signal cycle pure tone is got by the function of the single analysis and processing in the CVI.The main design of the hardware to export wable tone constructed by the pure tone is also introduced in this paper.And the starting point to make continuation and optimization of the system is also introduced
