| 摘 要： | 为了降低传统函数信号发生器成本,改善函数信号发生器低频稳定性,本文结合FPGA和51单片机设计并实现了产生以0.596Hz频率精度各种函数信号。函数信号频率、波形、幅度由51单片机控制,并用LCD显示函数信号相关信息。本文设计的信号发生器易维护、可以软件升级,从而得到更高频率精度的函数信号满足不同场合设计的需要。

| Abstract: | The article aims at the following two aspects of function generator: decreasing the traditional costing and promoting the stability of low frequency of function generator.The integration of FPGA and SCM 51 is designed hereby to make various signaling functions at 0.596Hz happen.SCM 51 controls the signal frequency,waveform and amplitude,whilst LCD displays the relevant information of signaling functions.It is possible for the generator designed to maintain,to upgrade the software so as to realize more accurate signal functions and to meet the needs at different occasions.The article here also contributes to the farther reform of nowadays’ higher education. |
