摘要
在EDA技术开发平台Quartus Ⅱ上设计实现了一种新型的2FSK信号调制解调器,利用m序列的随机性和确定性来产生输入基带信号,用分频器把时钟信号分频成两个不同频率的信号。详细介绍了基于FPGA的2FSK信号发生器的设计方法,提供了VHDL源代码在Quartus Ⅱ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,并在ACEX1K系列FPGA上硬件实现,具有较高的实用性和可靠性。
To design and achieve a new FSK modem based on EDA technology development platforms of Quartus Ⅱ , use pseudo-random sequence to generate the importation of base-band signal, with crossover frequency of the clock signal into two different frequency signals.Provide details on the FPGA-based FSK signal generator design and simulation results with VHDL source code provided in the Quartus Ⅱ environment. The whole design is implemented on FPGA based on the development platform Quartus Ⅱ with the characteristics of high relevance and reliability.
