摘要
提出一种信号发生器的设计,采用ALTERA cycloneII EP2C35F676C为主控芯片,采用直接数字频率合成技术,通过数码管和键盘与人交互,能够产生可调频率的正弦波,方波,三角波和锯齿波.通过硬件系统测试,结果表明系统精度较高、带负载能力较强、运行稳定,且能对信号实现峰值检波功能.
This paper presents the design of a signal generator, using ALTERA cycloneII EP2C35F676C as the main control chip, with direct digital frequency synthesis technology, through the digital tube and keyboard to interact with people, can have adjustable frequency sine wave, square wave, triangle wave, sawtooth wave.Through the hardware test, the results show that the load capacity is strong, the precision of the system is high, the operation is stable, and can realize the signal peak detection function.
