基于信号与系统理论的多媒体故障分析方法研究

Research on Analytical Technique of Multi-media Systems' Malfunction Based on Principles of Signals and Systems

多媒体系统因其设备与线路较为繁杂,发生故障时往往难以定位设备故障或线路问题。根据信号与系统理论,提出了多媒体故障的信号路径分析方法,归纳了该方法的两个操作步骤,简要分析其通用性,并综合运用该方法对常见的多媒体教学系统故障进行了示例分析,证明了该方法的有效性。

When multimedia systems are malfunctio ning, it is hard to find out their faulty parts because their constructions usually are complex. So, based on principles of signals and systems, a novel technique is introduced to analyze its fault when one system is under malfunction. Then the operation steps of the method are summed up, and its versatility is concluded briefly. At last, its effectiveness can be proved by applying the technique to practical examples.
