摘　　要：音频信号发生器是测量声音信号处理设备性能指标必不可少的仪器,文章首先论述了声音信号发生器的研究现状,然后针对现有技术存在的问题,提出一种可分别调节输出电压的占空比、频率、幅度的脉冲波形可调的声音信号发生器,且该声音信号发生器的占空比、频率、幅度可实现单一的调节。最后针对设计的信号发生器进行了实验,实验结果表明文章提出并设计的新型脉冲波形可调的声音信号发生器实用且具有明显的优势。Audio signal generator is essential equipment to measure the sound signal and deal with equipmentperformance. The paper compendiously summarizes the overseas and domestic research status of voice signalgenerators. Then we put forward a new voice signal generator to solve the problems of existing technology, in which theduty ratio of output voltage, frequency, amplitude adjustable pulse waveform of the voice signal generator can beadjusted respectively, and the sound the duty ratio, frequency and amplitude of the signal generator can realize thesingle adjustment. The experimental results show that the proposed new type of pulse waveform with adjustable voicesignal generator is practical and has obvious advantages.
