Title: Yasuji Saito: Innovator in Signal Processing Technologies
Introduction
Yasuji Saito is a prominent inventor based in Gunma, Japan. He has made significant contributions to the field of signal processing, holding a total of 12 patents. His innovative work has led to advancements in adaptive filtering and noise suppression technologies.
Latest Patents
Among his latest patents, Saito has developed an adaptive filter that includes a filter configured to perform a filtering process for an input signal. This filter outputs the processed input signal as an output signal. The invention also features a calculating unit that calculates a value indicative of an error between the amplitude of the output signal and a reference amplitude. Additionally, it includes an output unit that outputs a first constant as a parameter when the amplitude of the output signal exceeds a predetermined amplitude. Conversely, it outputs a second constant when the amplitude is below the threshold. An updating unit is also part of the design, which updates the filter coefficient to reduce the error.
Another notable patent is a noise suppression apparatus. This apparatus comprises a complex signal generation unit that converts an intermediate frequency signal into a complex signal. It also includes a noise detection unit that detects whether the variation in the level of the complex signal exceeds a predetermined threshold, indicating the presence of noise. A noise suppressing unit is designed to suppress the level of the complex signal if the variation exceeds the threshold.
