Latest Patents
Ogawa's latest patents include a "Distortion Measuring System Method Utilizing Signal Suppression." This method provides a way to test and measure distortion in electrical devices. It involves a signal generator that produces a signal with known phase, amplitude, and frequency, which is then supplied to both the device under test and a measuring unit. The measuring unit captures the output's amplitude, frequency, and phase rotation, which are then used to generate a suppression signal. This suppression signal is added to the output signal to suppress the fundamental wave, allowing for accurate distortion factor determination.
Another significant patent is the "Apparatus for Measurement by Digital Spectrum Analyzer." This invention divides the frequency range of measurement into multiple regions. For each region, a suitable test signal is generated and supplied to the device under test. The output is converted into a digital signal and analyzed using fast Fourier transform. The sensitivity of the AD converter is optimized for each region, ensuring accurate signal level conversion.
