Abstract:The design method of normal frequency standard signal source, which utilizes program control digital wave synthesis technology and achieved by microcontroller was given. Firstly, which gets the data that wave type needed by the calculation of software. Secondly, which utilizes D/A to achieve the conversion between digital and analogical. Thirdly, which outputs normal frequency voltage and current wave type by smoothness fliter and amplifier. The AT89C52 microcontroller is the hardcore of the hardware. The interface between users and computer utilizes keyboard enactment and the LCD display. The software utilizes by C51.
Keywords:normal frequency  digital wave synthesize  AT89C52
