Title: Yasunori Tani: Innovator in Digital/Analog Conversion Technology

Introduction

Yasunori Tani is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of digital/analog conversion technology, holding a total of six patents. His innovative work has advanced the capabilities of electronic devices, enhancing their performance and efficiency.

Latest Patents

Tani's latest patents include a D/A conversion apparatus designed to minimize the increase in circuitry when the number of output levels is increased. This apparatus converts a digital input value into a word length limited digital signal with a high sampling frequency, utilizing a digital filter and a noise shaper. The output is then mapped by a decoder to n m-valued signals in a cyclic manner, ensuring that the sum of these signals equals the digital input value. The n m-valued signals are subsequently converted into corresponding analog signals, which are summed to produce an analog output signal.

Another notable patent is a digital/analog conversion apparatus that effectively suppresses harmonic distortion at the outputs of a row of 1-bit digital/analog converters. This invention converts a digital input into a digital signal with p values at an elevated sampling frequency. A decoder circulates the assignment of value "1" among the 1-bit signals while designating an inhibit bit position. This innovative approach allows for the integration of analog signals by a row of uniform 1-bit digital/analog converters.
