摘 要 本设计使用VHDL语言在EDA技术开发软件Quartus上现模块化的二进制键控信号（ASK信号）的调制解调。本文主要介绍了VHDL语言的特点及其应用领域。通过对二进制监控信号（ASK信号）的工作原理分析，根据各系统的功能和硬件特点，设计总体框图，实现了二进制键控信号（ASK信号）的调制与解调模块的应用。并给出相应得仿真波形分析。同时在此基础上，我们为了加深对二进制键控信号（ASK信号）的理解，了解了多进制振幅信号（MASK信号），实现了多进制振幅信号（MASK）的调制的VHDL语言设计和波形仿真。 关键字：VHDL;ASK信号；调制解调；仿真波形；MASK信号 ABSTRACT The modular design using VHDL language binary keying signal (ASK signal) modem technology development in EDA software QuartusII. This paper describes the characteristics and applications VHDL language. By monitoring the binary signal (ASK signal) analysis works, according to the function of each system and hardware characteristics, design the overall block diagram of the signal to achieve the application binary keying (ASK signal) modulation and demodulation module. And accordingly have given simulation waveform analysis. On this basis, at the same time, we have to deepen their understanding of the binary signal keying (ASK signal) understanding and knowledge of the multi-band signal amplitude (MASK signal), to achieve a multi-band amplitude signal (MASK) of VHDL language design and modulation waveform simulation.
