摘要
设计了基于单片机AT89S52和MAX038的信号发生器,用于产生频率和幅度均可程控调节的正弦波、方波和三角波信号。MAX038函数发生器配以少量外围器件负责产生波形,波形再经过LM6361宽频电压放大和一级功率放大电路输出。主控器AT89S52负责波形种类选择、频率调节、输出幅度调节、液晶显示、键盘操作等各个模块的工作。
Signal generator based on AT89S52 and MAX038 can generate sine, pulse and delta wave that their frequency and range are adjustable. MAX038 is configured by few components and generate wave. Wave is gained by LM6361 and powered up. MCU AT89S52 controls wave type choice, frequency and range adjusting, LCD displaying, keyboard and so on.
