Abstract(in English) We have proposed the new adaptive frequency estimation algorithms based on the time domain control. The signal processing by the time domain control has not been considered and this processing may show the new possibility of the signal processing. This paper proposes a new adaptive frequency estimation method using the delay time control by the zero cross detecting of the notch filter output. The frequency estimation is done from the interval between the zero crosses for a single sinusoid which is separated by the l-1 cascaded notch filters. Then the number of the delay elements of the notch filter is adapted based on the estimated frequency. We examine the performance of the proposed frequency estimation method by the computer simulations, and show that this method can estimate accurately the sinusoidal signals in additive noise.
