The Design of Computer Interfering System Based on Direct Digital Frequency Synthesizer Technology
Xiong Shi · Journal of Wuhan Polytechnic University · 2008
This paper introduces the built-in computer interfering system based on Direct Digital Frequency Synthesizer(DDS) technology.This system regards single-chip as control core,writes the pseudo random array produced by the algorithm of Monte Carlo into the digital and programmable DDS chip as control words.Finally it realizes the noise modulation from the DDS export Signal.
