Latest Patents

Moriya's latest patents include a digital-to-analog converter and a digital-to-analog converting method. This invention features a pulse-width modulation signal generator that creates a pulse-width modulation signal by modulating an actual set value with a count value. Additionally, it incorporates a low-pass filter designed to eliminate high-frequency components from the pulse-width modulation signal, thereby outputting an analog signal. The method calculates the actual set value by multiplying the difference between the current target digital value and the previous target digital value by a coefficient derived from the time constant of the low-pass filter and the cycle of the target set value. Furthermore, he has developed a reception apparatus where the level crossing number counter section obtains the Doppler frequency caused by fading by counting the number of times a received signal crosses an averaged received signal level. This technology allows for precise control of reference signal correlation integration based on the Doppler frequency.
