Yu Wang · Yuhang jice jishu · 2004
Direct Digital type Synthetic (DDS)technology as a kind of frequency synthetic new technology has developed in last few years. The output of DDS has wide relatively bandwidth, short frequency conversion time, high frequency resolulion capacity, continuous output phase, broadband orthogonality signal generation and DDS is integrated easily. It shows extensive application prospect in many electronic field such as communication, radar, remotely control, telemetering, electronic confrontation, electronic expand frequency and modernization instrument meter industry. This paper introduces the application condition and the characteristic of DDS and it also elaborates the basic principle of DDS and makes mutual contrast for its some synthetic methods in application.
