本文介绍了数字计算式频率合成器的基本原理,提出了一种采用标准晶振作为时钟源的合成器方案,给出了一般的设计公式,并在实验中得到验证,基本达到设计要求。最后阐述了这种新型频率合成器的优点及其应用。
This paper introduces the basic principle of digital synthesizer and presents a synthesizer scheme using a standard crystal oscillator as a clock source. The general design formula is given and verified in the experiment, basically meeting the design requirements. Finally, the advantages and applications of this new type of frequency synthesizer are described.
