Title: Hama Mitsuji: Innovator in Digital Modulation Technology

Introduction

Hama Mitsuji is a notable inventor based in Gifu, Japan. He has made significant contributions to the field of digital modulation technology. His innovative work has led to the development of a unique digital modulator that enhances signal processing capabilities.

Latest Patents

Mitsuji holds a patent for a "Digital Modulator and Baseband Signal Generator for Digital Modulator." This invention includes a signal source for a digital baseband signal and a signal source for carrier phase information. The digital baseband signal is converted into amplitude information of an I phase, a Q phase, an I' phase, and a Q' phase by a mapping circuit. The carrier phase information is transformed into four phase information with phases shifted by shift registers to be out of phase by π/4 from each other. The digital modulator comprises four ROMs, each outputting a multiplication result of the corresponding amplitude information and carrier signal. These outputs are added digitally and converted into an analog signal, which is supplied as a modulated signal.
