A method for assessment and processing of biomedical signals containing trend and periodic components.
A method for assessment and second-order polynomial detrending of signals containing periodic components is proposed. The analytically derived properties of this method are validated with synthesized signals, processed by the computational procedure developed. It is shown that, in addition to accurate detrending, the proposed method reveals the periodicity of various biomedical and other types of signals and thus contributes to performance improvement of their spectral analysis. An application to processing of R-R interval series is presented.
