Title: The Innovations of Moto Yamada
Introduction
Moto Yamada is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of audio technology, holding a total of 4 patents. His work focuses on enhancing audio signal processing, which has implications for various audio applications.
Latest Patents
Yamada's latest patents include an audio circuit and a reproduction method of DSD signal. The audio circuit features a volume circuit designed to process a DSD signal that contains DSD data and a DSD clock. This volume circuit incorporates a first shift register that holds N bits of the DSD data, along with a replacement circuit that replaces (N−M) bits corresponding to a gain set value with a mute bit string having a mark rate of substantially 50%. Additionally, his level adjusting circuit is configured to adjust the level of an audio signal. It includes filters that receive the audio signal and pass a specific band set for each filter. Variable gain amplifiers are provided for each filter, amplifying the output signal accordingly. An adder sums the input audio signal with the output signals of the variable gain amplifiers, while a control unit manages the level of the output signal and the gain of each amplifier based on monitored levels.
