| Abstract: | With the development of DSP(digital signal process) and IC(integrated circuit) technology,DDS(Direct Digital Synthesizer)is applied more and more widely.This paper mainly introduces a method that can directly realize the multi-system digital modulation in the 70 MHz.through the digital combination of AD's high-performance DDS chip-AD9852 and FPGA(Field programmable Gate Array).The long-distance transportation of signals will come true through FPGA programming which can control the diverse modulation signals... |
