基于AT89S51单片机的低频信号设计及仿真研究

摘要

In this paper,to design a simple signal generator using AT89S51 SCM,through the DAC0832 conversion and restore the waveform signal,get the corresponding square wave,sawtooth wave,triangle wave and sine wave signal.Based on the circuit design,this paper also proposed free transform,phase and frequency adjustable technology design for the four kinds of waveforms,and has carried on the simulation debugging.%文中采用AT89S51单片机来设计简易的信号发生器,通过DAC0832转换并还原了波形信号,得到了相应的方波、锯齿波、三角波和正弦波等波形信号.在电路设计的基础上,本文还对上述4种波形进行了波形自由转换、相位和频率自由调节等技术设计,并对其进行了仿真调试.
