| Abstract(in English) | A design of digital filters for separating a quasi-periodic signal from the noise-corrupted observation is presented. It is derived from digitization of the Kalman filter equation based on a quasi-periodic signal model involving Brownian amplitude/phase fluctuations, It will be shown that the obtained transfer function has not only a comb structure for extracting each harmonic component but also a notch structure for suppressing interference between harmonics components. The validity of the proposed filter is confirmed through some numerical experiments using the synthesized quasi-periodic signals. |
