一种低成本数字信号发生器的研制

Design on a low-cost digital signal source

随着科技的不断进步,电子信息技术也得到了长足的发展,这也使得信号源等电子设备的应用更加广泛。从信号源的成本、功能以及功能的拓展性等方面考虑,以DDS为主要部件,51系列单片机为主控芯片,研制了一种低成本数字信号发生器。

With the advance of science and technology, electronic information technology also has madeconsideration progress. Therefore, the signal source and other electronic equipments become moreincreasingly important. In view of the cost, the function and functional extendsibility, DDS is the mainresearch object in the design, in which single chip microcomputer serves as the main control chip and itputs forward a manufacture method of making a simple signal source.
