Title: Yuki Hayashida: Sampling-Rate Conversion Innovation.

Introduction

Yuki Hayashida is an inventor associated with Kanagawa, Japan, and NTT Innovative Devices Corporation. The supplied information identifies one patent associated with Hayashida.

Latest Patents

Hayashida’s patent, “Sampling Rate Converter, Sampling Rate Conversion Method, and Communication System,” describes a system for converting input signals sampled at one rate into output signals sampled at a rate determined by a conversion ratio of M/N. Its design uses a digital filter with multiple polyphase sub-filters, route-selection circuitry that directs input signals to the appropriate sub-filters, and a multiplexer that combines their outputs in the required order. This approach supports sampling-rate conversion through coordinated filtering and output sequencing.

Career Highlights

The available information connects Hayashida’s work to NTT Innovative Devices Corporation and identifies the sampling-rate conversion patent as a technical contribution in digital signal processing. The patent addresses components used in communication systems that need to process signals at different sampling rates.
