摘要
比较了各种波形发生器特点,给出了一种以CPLD为核心的,多频点的正弦波发生器的设计方法,详细描述了硬件的组成及核心CPLD功能模块的构成。经过实验,结果表明该波形发生器能够正确产生仪器工作所需约12 000种频率值的正弦波,输出信号具有很高的精度及稳定度。
Comparing the characteristics of various waveform generators, this paper introduces a design method of multi-frequency sine- wave generator based on CPLD. It also descrfaes the composition of hardware and the composition of CPLD functional modules. Experimental results show that the sine-wave generator could generate sine wave at about 12 000 kinds of frequency val- ues correctly, and the output signals are of higher precision and stability.
