Title: Innovations of Yoshiyuki Tsuchikane
Introduction
Yoshiyuki Tsuchikane is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of digital audio technology. With a total of 4 patents to his name, Tsuchikane has developed innovative systems that enhance audio processing and editing.
Latest Patents
One of his latest patents is a "Characteristic control system for a digital equalizer." This system comprises a digital equalizer constructed from a digital filter, which directly provides a desired equalizing characteristic for a digital pulse-modulated signal. The control part of this system allows for changing the equalizing characteristic from a first arbitrary characteristic to a second arbitrary characteristic, enabling the achievement of one or multiple intermediate equalizing characteristics before reaching the desired second characteristic.
Another significant patent is the "Digital editing system for audio programs." This system includes first and second memories for storing audio data and weighting factor data, respectively. The audio data is retrieved sequentially from the first memory and multiplied by corresponding weighting factor data from the second memory. A coincidence detector identifies when specific storage locations of the memories are accessed. The weighting factor data varies over time, allowing for the creation of 'fade-out' and 'fade-in' patterns in audio programs, which can be combined to produce a continuous audio output.
