| Abstract: | 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. |
