Latest Patents

Hosoi holds a patent for a data processing method for spectrum analyzers. This method enables a calculation-based signal analyzer, such as an FFT-based spectrum analyzer, to produce results akin to those of a swept spectrum analyzer employing a video bandwidth (VBW) filter. The process involves producing a spectrum, replacing the frequency axis with a corresponding time axis, and applying a time domain filter. The filter characteristics are achieved by performing an FFT to generate frequency domain data, multiplying by the frequency response, and then performing an inverse FFT to produce a filtered version of the display spectrum data.
