为了设计一款结构简单、性能优良的信号发生器,采用了AT89C51单片机为控制核心.在Proteus下仿真可以产生正弦波、方波、三角波、锯齿波.而且可以方便地设定输出信号的频率及幅度,得到的输出波形失真度低,频谱纯度高.%In order to design a signal generator which has simple structure and excellent performance.AT89C51 was used as the control core of the signal generator.The signal generator could generate sine wave, square wave, triangle wave and sawtooth wave when it was simulated in Proteus, the frequency and the amplitude of the output signal could be set easily.The output waveform of simulation in Proteus has low degree of distortion and high purity of frequency spectrum.
