Latest Patents

One of Kazuo Tsukada's latest patents is the **Digital Loop Filter**, designed for use in phase-tracking circuits adaptable to systems like the DECCA system. This digital loop filter incorporates a feedback circuit that receives a digital input signal and produces an output signal, which is then fed back into the system after a predetermined delay. Additionally, it features a feed-forward circuit that multiplies the input signal by a constant and combines it with the feedback signal to output a refined digital signal.

Another notable invention is the **Hyperbolic Navigation Receiver**, which facilitates the identification of vessel locations by phase-locking output signals from voltage-controlled oscillators or phase shifters. This invention allows for effective tracking by analyzing incoming signals from master and slave stations without requiring a multiplier for phase discrimination. Tsukada's inventions illustrate a deep understanding of complex navigation mechanisms and their practical applications.
