摘要
该信号发生器以AT89C52单片机和DAC0832芯片为核心进行设计。单片机和D/A芯片通过直接数字合成技术来生成正弦波、三角波和方波,波形的类型和幅度在一定范围内可变。介绍了该信号发生器波形产生的原理、硬件电路和软件编程。该信号发生器具有价格低、性能稳定、升级方便的优点。
The waveform generator figured the AT89C52 and DAC0832 as the hardcore.The microcontroller and DAC0832 generate sine wave,triangle wave and square wave by the technologies of direct digital frequency synthesize（DDFS）.The type and scope can be changed in the certain range.It introduced the theory of wave generation,hardware and software.The waveform generator has the merit of cheap,stability capability and facility upgrade.
