摘要
介绍了一种基于MAX038的多功能信号发生器的基本组成及设计,该发生器采用单片机控制,可以产生三角波、方波、正弦波和PWM信号,也可对外部频率信号进行测量。发生器采用键盘和上位机设置波形发生器的各种参数并实时显示输出频率值。
The basic structure and design principle of a multi-function signal generator based on MAX038 are introduced, which is controlled by microcomputer. It can produce triangle, square, sine waveforms and PWM signal, and it can be used as Instrument of Frequency measure. The control parameters are preset and transmitted to MCU by different control mode. The current output frequency will be sent back and displayed in the CRT and LCD.
