摘　　要：时钟电路在数字电路中占有重要位置,对实现数字电路的功能起决定作用。如果从计算机安全方面考虑,时钟电路同时又是产生电磁辐射的主要来源。本文对计算机时钟信号给出了相关的时域、频域特征,同时对其电磁信息泄漏进行了详细地理论分析。The clock,which is the decisive factor to carry out the function of digital circuit, plays an great important role in circuit digital circuit. As in the salty of computers, the clock circuit is also the main resource to generate electromagnetic information leakage. In this paper ,they are given that the correlated the time-domain and frequency-domain characters and also that a detailed analysis of the electromagnetic information leakage of clock signal In theoretical.

关 键 词：时钟信号 电磁辐射 电磁信息泄漏 TEMPEST
