信号发生器是指产生所需参数的电测试信号的仪器。按信号波形可分为正弦信号、函数（波形）信号、脉冲信号和随机信号发生器等四大类。信号发生器又称信号源或振荡器。各种波形曲线均可以用三角函数方程式来表示。能够产生多种波形，如三角波、锯齿波、矩形波（含方波）、正弦波的电路被称为函数信号发生器。-Signal generator is to generate the required parameters of the electrical test signal equipment. Sinusoida

硬件电路主要分为信号转换电路、分频电路、数据选择电路、单片机系统和显示电路五部分。
电平转换电路：
电平转换电路的必要性：因为在单片机计数中只能对脉冲波进行计数，而实际中需要测量的频率的信号是多种多样的，有脉冲波，还有可能有正弦波、三角波等，所以需要一个电路把待测信号可以进行计数的脉冲波。
通过电平转化电路将正弦输入信号fx整形成同频率方波fo,要将正弦信号转换成方波信号可以用过零比较电路实现。正弦信号通过LM833N与零电平比较，电压大于零的时候输出LM833N的正电源+5V
