Abstract :
In this paper, we propose adaptive digital filtering based on a continuous-time performance index under the situation where the continuous-time output of an unknown system can be observed. It is shown that a recursive formula is derived by the lifting technique. Moreover, we consider an implementable case where the output of the unknown system is approximated by the oversampled discrete-time signal.
