| Abstract: | Based on a project concerning a certain communication measuring device,this paper introduced a method to achieve intermediate frequency digital signal generator with software radio.The paper consists mainly of the hardware method to build the frame of the digital system and the orthogonal algorithms of several general modulations which are used in DSP software.Finally,the testing results of the digital system are given to prove that this method to achieve intermediate frequency digital signal generator is proper and feasible.Seven kinds of signals,either analog or digital,could be generated by this generator,all of which could satisfy the needs of project.In addition,good in flexibility and wide in extension make the intermediate frequency digital signal generator easy to be upgraded. |
