Title: Masanori Ienaka: Innovator in Digital Signal Processing
Introduction
Masanori Ienaka is a prominent inventor based in Kodaira, Japan. He has made significant contributions to the field of digital signal processing, holding a total of 18 patents. His work focuses on enhancing the efficiency and functionality of electronic systems.
Latest Patents
One of Ienaka's latest inventions is the phase coincidence detector. This device examines whether two input digital signals are coincident by utilizing delay and advance signals from a digital phase comparator. The phase comparator assesses the phase difference between the two signals and outputs delay and advance signals that represent their respective timing discrepancies. The innovation includes a pulse width discrimination circuit that samples these signals to indicate in-phase and out-of-phase states.
Another notable invention is the power-saving intermittently operated phase-locked loop. This technology aims to stabilize the oscillator frequency when an electric power source is turned on. It detects the moment when the phase difference between clock signals becomes nearly zero and initializes the frequency dividers accordingly. This approach prevents significant frequency changes during power activation.
