摘要
数值控制震荡器(NCO)是一种通信领域广泛使用的装置。文章首先介绍了数值控制震荡器的工作原理,然后重点介绍一种基于现场可编程门阵列(FPGA)的NCO的电路设计,采用Verilog语言描述硬件电路,在QuartusⅡ平台上进行设计和仿真,并给出了电路的仿真波形,电路易于用FPGA器件实现,具有良好的应用前景。
Numerically Controlled Oscillator is a widely using device in communication field.This paper firstly introduces the working theory of Numerically Controlled Oscillator.Then especially presents a circuit design of NCO based on FPGA,which describes the hard circuit by Verilog .It is designed and simulated in Quartus Ⅱ environment.And the simulation wave is provided. It has good application prospects because it is easily implemented by FPGA device.
