Results show that PLL is of the factors such as loop filtering ripples,pre-filtering delay and PLL loop filtering delay,which can cause insu.
结果表明,PLL存在环路滤波纹波、前置滤波延迟和自身滤波延迟等方面的因素,对PLL的频率跟踪精度产生不良影响,且无法消除。
A design method of tapped delay line filter (transversal filter) based on real genetic algorithm isproposed.
