摘要
介绍一种采用８０３１单片机控制的压控低频信号源，可以在１００Ｈｚ～２００ｋＨｚ的频率范围内输出连续可变的正弦波信号和方波信号。
Presented in this paper is a low frequcncy signal source controlled by 8031 single chip microcomputer.The source can transmit continuously changeable sinusoidal waves and square waves at the frequency ranges between 100 Hz～200 kHz,and can also display the frequencies of the trasmitted signals on LED.
