提出了一个睡眠时相事件模型，如顶波、K波、δ波和睡眠纺锤波。它由由白色噪声（模拟紧张性Delta和Sigma活动）和孤立随机脉冲驱动的反馈回路组成，根据背景紧张性活动模拟顶波或K复合波。一种基于模型的方法用于检测睡眠时相事件在个人计算机上实现。它的性能进行了研究，使用模拟和真实的整夜EEG信号。该方法是能够检测K复合波和顶点波在一个可靠的方式，尽管他们的可变形状和在存在各种背景activity.The检测器似乎有上级性能到目前为止在文献中报道的检测器的性能进行了比较，还使用正常的睡眠EEG记录的8小时持续时间从6个科目的脑电图。在准确性和可靠性方面的性能是令人满意的。在睡眠的第3和第4阶段检测K复合物的问题进行了讨论。
A model of sleep phasic events such as vertex waves, K complexes, delta waves and sleep spindles is proposed. It consists of feedback loops that are driven by white noise (simulating tonic delta and sigma activity) and by isolated random impulses, simulating vertex waves or K complexes, depending on the background tonic activity.A model-based method for the detection of sleep phasic events was implemented in a personal computer. Its performance was investigated using simulated and real whole-night EEG signals. The method was able to detect K complexes and vertex waves in a reliable way in spite of their variable shapes and in the presence of a variety of background activities.The detector appears to have superior performance to those so far reported in the literature.The performance of the detector was also compared to that of an electroencephalographer using normal sleep EEG records of 8 h duration from 6 subjects. The performance was satisfactory both in terms of accuracy and reliability. The problem of detecting K complexes in stages 3 and 4 of sleep is discussed.
