本文讨论使用过零检测器的全数字锁相环在噪声干扰下每鉴相一次后其固定校正步数大于1情况下的性能。先讨论校正两步时的性能,并给出几种性能曲线,然后讨论校正步数大于2时的性能分析方法。
This article discusses the performance of a full digital phase-locked loop using a zero-crossing detector with a fixed number of correction steps greater than one after each phase-detection under noise interference. Discuss the performance of two steps of correction, and gives several performance curves, and then discusses the method of performance analysis when the number of calibration steps is greater than 2.
