| Abstract(in English) | In this paper, we propose an adaptive signal processing system for detection of narrowband signals with unknown frequency components. The proposed system consists of a variable band-stop IIR digital filter that is designed by the Constantinides frequency transformation. We show that the proposed system easily realizes the adaptive control of the variable band-stop niters with arbitrary transfer functions by means of simple mathematical formulae. We also show that the proposed system includes the well-known all-pass-based adaptive notch filters as a special case. Furthermore, we give a simulation example to demonstrate that the proposed system attains higher signal-to-noise ratio at the filter output than the adaptive notch filters. |
