In this paper, the model of an existing superheterodyne receiver system with poor performance is built and solved in order to depict the frequency selectivity curve of the entire receiver system. In addition, the main intermodulation products which will bring strong power and fall into the actual receiving channels are theoretically predicted. Meanwhile, to(More)
In order to improve and reinforce the facilities with problems on electromagnetic compatibility, it is inevitable to get down to the suppression and improvement to the interference source first. If the computer modeling to the interference source could be undertaken before the correctness, then by means of simulation the best method is to be found to(More)
