Introduction

Takahiro Hata is an inventor associated with Kanagawa, Japan, and NTT Innovative Devices Corporation. His listed patent concerns digital signal processing and sampling rate conversion.

Latest Patents

Hata is credited with 1 patent: “Sampling Rate Converter, Sampling Rate Conversion Method, and Communication System.” The invention converts input signals sampled at one rate into output signals sampled at a rate defined by the conversion ratio M/N. It uses a digital filter composed of polyphase sub-filters, with coefficients selected according to that ratio. Route-selection circuitry directs input signals to the appropriate sub-filters, and a multiplexer combines their outputs in a determined order to produce the converted signal.

Career Highlights

The available information associates Hata with NTT Innovative Devices Corporation and identifies his work on sampling rate conversion. The patent describes an approach intended to support conversion between input and output sampling rates through coordinated filtering and signal routing.
