Abstract: According to the problem of compromising emanation information caused by horizontal synchronous computer signal, this paper presents a correlative detection algorithm for extracting the information, and introduces a strategy of extracting synchronous information with Matlab simulation. The implementation of the algorithm on Digital Signal Processing(DSP) is given, and the experiment is performed on the ICETEK- C6713-A EVM platform, whose results prove the robustness of the method.

Key words: Digital Signal Processing(DSP), compromising emanation, synchronous information
