Title: **Naohiro Toki: Innovator in A.C. Signal Detection**
Introduction
Naohiro Toki is a distinguished inventor hailing from Hyogo, Japan. He has made significant contributions to the field of signal detection, specifically concerning alternating current (A.C.) signals. With a total of six patents to his name, Toki's innovations stand out for their technical intricacies and practical applications.
Latest Patents
One of Toki's latest patents is an apparatus designed for detecting the amplitude and phase of an A.C. signal. This apparatus incorporates a signal detection circuit that effectively identifies the A.C. signal, which is then processed by a signal splitting circuit. This circuit divides the detected A.C. signal into two outputs, the first and second A.C. signals, which are 90 degrees out of phase with each other.
The signal splitting circuit comprises a first order lag circuit alongside a subtractor and two amplifying circuits. Additionally, Toki’s apparatus includes a phase compensation circuit that receives the split A.C. signals, advancing the output phase by the characteristic phase lag. This circuit also integrates an amplitude and phase detection subsystem which detects the amplitude and phase by implementing a polar coordinate transformation of the received signals.
