| Abstract(in English) | Biological signals such as electroencephalogram(EEG), electroretinogram(ERG), electromyogram(EMG) or electrocardiogram(ECG) are contaminated by large power-line interference. In spite of modern high performance instrumentation amplifiers, there are many cases in which it is difficult to remove such alternative noise entirely. A possibility of adaptive filters for removing such noise is known. However, in the fields of biological signals, few detailed discussions about the adaptive filters are given. In this paper we perform numerical experiments in which the adaptive algorithms(LMS and RLS) fail in removing such alternative noise in the case that the amplitudes of harmonics of alternative noise are not same. And we show that a reason for this phenomenon is that the condition number of the covariance matrices of these signals become high when the amplitudes of harmonics differ each other. |
