基于VHDL语言的数字波形发生器的设计

Design of Digital Waveform Generator Based on VHDL

阐述了数字波形发生器系统的设计方案,给出了系统的原理框图,并对设计功能进行了描述;详细介绍了系统主要功能模块的作用和工作原理,并对部分模块在MAX+PLUSII10.2中进行了仿真;仿真结果表明,系统能够产生正弦波、方波、三角波和锯齿波,产生的4种波的频率、幅值可以调节,还可以通过4位数码管显示输出波形的频率。

The plan for a digital waveform generator is expounded; the functional block diagram of this system is gived, and the function is described;the effect and principle of major modules is introduced detailedly and part of modules are simulated by MAX PLUSII10.2;the simulation indica ted： this system can produce sine, square, triangle wave, sawtooth, the frequency and amplitude of the four kinds of wave can be adjusted, and the frequency of output waveform can be displaied through 4 sections of numerical code tubes.
