波形发生器是一种常用的信号源,广泛地应用于电子电路、自动控制系统和教学实验等领域。目前使用的波形发生器大部分是利用分立元件组成的,其体积大,可靠性差,准确度低。本文介绍一种用8031单片机构成的波形发生器,可产生方波、三角波、梯形波、锯齿波、正弦波和脉冲信号等多种波形,波形的周期可 Waveform generator is a commonly used signal source, widely used in electronic circuits, automatic control systems and teaching experiments and other fields. Most of the waveform generators currently used are made up of discrete components, which are large in size, poor in reliability and low in accuracy. This article describes a 8031 ​​single-chip form with a waveform generator can produce square wave, triangle wave, trapezoidal wave, sawtooth wave, sine wave and pulse signals and other waveforms, the waveform of the cycle can be
