Title: Hiroki Mouri: Innovator in Signal Processing Technologies

Introduction

Hiroki Mouri is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of signal processing, holding a total of 13 patents. His work focuses on advanced technologies that enhance the performance of digital systems.

Latest Patents

One of Mouri's latest patents is an orthogonal transform error corrector. This invention features a phase adjuster that arranges the phases of waveforms of a complex signal after orthogonal transformation. An edge detector identifies the edge of the complex signal post-phase adjustment. Additionally, a phase shift detector measures the phase shift of the output signal from the edge detector, producing a phase error signal (PE). The oscillator, connected to mixers and a shifter, performs the orthogonal transform and includes a phase adjustment section that corrects the phase shift of the original signal based on the PE.

Another notable patent involves a digital PLL circuit, semiconductor integrated circuit, and display apparatus. In this invention, a phase comparison circuit counts the transitions of a reference clock and an oscillation clock. It sets a time period for phase comparison and detects a phase error value based on the difference between a target count value and the number of transitions of the oscillation clock. A smoothing circuit then processes the phase error value, while a digitally-controlled oscillation circuit adjusts the frequency of the oscillation clock accordingly.
