In scientific research, production and engineering education practice, such as the field of teaching experiments, industrial process control, biomedical, etc. often need to use low-frequency signal generating source. Signal generator as a generic electronic equipment, in production, research, monitoring and control, communications and other fields have been widely used. The system is a simplified design of low-frequency signal source, through the control keys, D / A conversion circuit and the external low frequency signal generating function. This system can output a triangle wave, sine wave, square wave. Key words: low-frequency signal, source single-chip, D / A converter,目 录1 绪论...............................................................................11.1 课题讨论的背景...............................................................11.2 国内外波形发生器技术进展.....................................................11.3 课题讨论的目的及意义.......................
