摘　　要：通过对啭音信号进行简化处理,将复杂的啭音信号转换为简单的纯音信号。在此基础上,利用DDS技术对纯音信号进行数字化处理,并通过CVI强大的信号分析和处理函数得到单周期纯音信号所对应的离散幅值,同时设计了硬件电路,对构造的啭音信号进行输出。此外,还提出了对该系统进行拓展的可行性及优化的着眼点。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.
