摘要
在介绍数字频率合成锁相环的基础上,详细分析了此环路对其鉴相器输出端具有特殊性质的寄生信号的抑制。证明此环路的输出寄生噪声抑制比是比较理想的。
Based on the introduction to a PLL for digital frequency synthesis,this paper describes on detail the suppression of the specific spurious signals occurring at the output of the phase detector of the PLL.The result shows that the output noise-to-carrier ratio is ideal.
