摘要
本文对直接数字频率合成(DDS)基本原理进行了简要介绍,提出了一种由DDS和直接频率合成(DS)构成的适用于宽带跳频通信系统的频率合成器设计方案。
The fundamental principle of direct digital synthesis DDS is introduced in this paper. A design of frequency synthesizer combining DDS with DS is given and this type of frequency synthesizer is especially suitable for wide-band frequency - hop system.
