2FSK信号产生器的FPGA设计

FPGA Design of 2FSK Signal Generator

在EDA技术开发平台上设计实现了一种新型的2FSK信号产生器,利用FPGA产生波形所需的数据,再通过D/A器件输出2FSK波形。详细介绍了基于FPGA的2FSK信号产生器的设计方法,提供了部分VHDL的源代码及在M ax+P lusⅡ环境下的仿真结果。整个系统的功能在EDA技术开发平台上均调试通过,具有较高的实用性和可靠性。

A new kind of 2FSK signal generator is realized on EDA experiment platform,utilizing FPGA to produce the data that the waveform needs ,and realizing output 2FSK by D/A device. This paper introduces a way for designing 2FSK signal generator,and provides a part of VHDL source code along with its simulation result in Max＋Plus Ⅱ . The emulations of waveform have been given. This system features have high reliability and good flexibility.
