Title: Hiroyoshi Oka: Innovator in Signal Measurement Technology
Introduction
Hiroyoshi Oka is a notable inventor based in Atsugi, Japan. He has made significant contributions to the field of signal measurement technology, holding a total of 3 patents. His work focuses on developing advanced systems for analyzing and measuring signal spectra.
Latest Patents
Oka's latest patents include a burst signal spectrum measuring system with stepwise sweeping. This innovative measuring unit converts a measuring signal into an intermediate frequency band of a predetermined bandwidth. It detects the intermediate frequency band while variably controlling a local oscillation frequency of a local oscillator. The system includes a waveform memory that stores the magnitude of a detection signal output from the measuring unit in correspondence with the frequency. An analyzing unit then analyzes the frequency component included in a signal to be measured based on the stored values. Additionally, he has developed a spectrum analyzer capable of displaying signals obtained during a measurement. This analyzer comprises various components, including a high-frequency signal processing circuit that frequency-converts an object signal into an intermediate-frequency signal. The output is a frequency spectrum of the object signal, which is then demodulated and displayed.
