| 摘 要： | 本文介绍一种1kHz 分辨率的频率合成器,该合成器可用于跳频电台,本合成器采用了数字鉴频鉴相器和吞脉冲技术,实现了在整个调频波段1kHz 分辨率的单环锁定.在此基础上提出了3种具体减少换频时间的措施,尤以独到的改变鉴相频率的方法,在不增加任何电路配制的情况下,大大缩短了换频时间.

| Abstract: | This paper introduces a kind of frequency synthesizer with lkHz frequen- cy resolution,which is used in hopping transceiver.Frequency and phase demodulators and swallowing pulse technique are used in the synthesizer to realize single loop lock at lkHz within the band of FM.Three practical ways of decreasing the converting time, esp.the one of changing phase demodulation frequency are introduced,which have nev- er been found in ealier literatures. |

| Keywords: | frequency synthesis by phase lock resolution swallowing pulsetechnique frequency converting time |
