Latest Patents

Kubo holds a patent for a "Circuit for demodulating PSK modulated signal by differential-defection." This invention simplifies the demodulator circuit's construction by converting a PSK modulated signal into a quasi-base band signal, which is then subjected to complex separation. The differential-detector circuit processes only the phase angle sampled from a digital complex signal, resulting in a straightforward design. The circuit compensates for errors between the carrier wave in the modulated signal and the locally oscillated frequency on the receiving side, outputting a digital demodulated signal.
