本文讨论锁相环具有高频环节时,该环节的时延引起捕获过程的频率反推、拒捕现象与假锁的固有关系。分析建立在Develet及Gardner所作工作的基础上,但修正了Gardner关于形成假锁的条件,同时指出Gardner关于假锁只能发生在牵引曲线的假零点处这种观点的局限性。文中还给出了环路不发生拒捕时各种参数间的关系。 This article discusses the phase locked loop with high-frequency link, the link of the delay caused by the frequency of the capture process of anti-pushback, rejection of the phenomenon and the inherent relationship between false lock. The analysis builds on the work done by Develet and Gardner but modifies Gardner’s conditions for forming a false lock and points out Gardner’s limitations on the false lock that can only occur at the pseudo-zero point of a traction curve. The paper also gives the relationship between the various parameters when the loop does not happen to reject.
