摘　　要：数字通信系统中的数字调制与解调技术包括幅度键控(ASK)、频移键控(FSK)和相移键控(PSK),而FSK是应用较广的一种调制与解调方式。利用VHDL语言设计了2FSK调制解调器,并通过QuartusⅡ仿真平台进行仿真验证,最后下载到FPGA芯片EP1K30QC208-2实现了2FSK调制解调电路。仿真及实验结果表明采用此设计方案是可行的,并具有速度快、可靠性高及易于大规模集成的优点。In the digital communication system,the digital modulation-demodulation technologies including frequency shift keying（FSK）,amplitude shift keying（ASK）and phase shift keying（PSK）are adopted,among which FSK is a widely-used modulation-demodulation mode. The 2FSK modulator-demodulator was designed with VHDL language,and was verified on simu-lation platform Quartus II. The 2FSK modulator-demodulator was implemented by downloading the related programming data files to FPGA chip EP1K30QC208-2. The simulation and experiment results indicate that this design scheme is feasible,and has the advantages of fast speed,high reliability and easy to integrate in large scale.
