Title: Yuji Kishi: Innovator in Spectrum Analysis
Introduction
Yuji Kishi is a prominent inventor based in Atsugi, Japan. He has made significant contributions to the field of spectrum analysis, holding a total of 3 patents. His work focuses on developing advanced technologies that enhance the measurement and analysis of frequency signals.
Latest Patents
Kishi's latest patents include a spectrum analyzer and a spectrum analysis method. The spectrum analyzer is designed to perform measurements promptly while preventing the display of spectrum waveforms caused by fractional spurious components. This is achieved by setting a reference signal frequency to a predetermined value and selecting a loop filter band that is narrower than the resolution bandwidth. Additionally, when the designated span width is smaller than a boundary value, the reference signal frequency is adjusted to increase the frequency differences between the fractional spurious components and the main signal component. This innovative approach effectively suppresses the levels of fractional spurious components.
Another notable patent is a signal analyzing apparatus that converts input signal frequencies into intermediate frequencies. This apparatus includes a sweeping unit that sweeps local oscillation frequencies, a filter that selectively passes signals, and an A/D converter that samples and converts these signals into digital data. The signal processing unit then processes this data to produce frequency spectrum data, ensuring accurate correlation between measured frequencies and stored data.
