Title: **Innovator Profile: Tatsuo Sawada**

Introduction

Tatsuo Sawada is a renowned inventor based in Sagamihara, Japan. With two patents to his name, his contributions to the field of technology, particularly in angle modulation systems, mark him as an important figure in innovation.

Latest Patents

One of Tatsuo Sawada's latest patents is the "Angle Modulated Wave Demodulation System". This system is designed to demodulate an input angle modulated wave utilizing a phase locked loop system. It features a phase comparator that operates responsively to the input angle modulated wave. The system also includes a voltage-controlled oscillator that is supplied with a part of the output from the phase comparator, which in turn regulates its oscillation frequency. Notably, the phase locked loop system is engineered with a lock frequency range that narrows when the input angle modulated wave level falls below a certain threshold. This innovative approach ensures optimal use of the lock range while maintaining synchronization with the input signal, oscillating at a frequency matching the carrier's center frequency when the phase locked loop loses lock.
