Latest Patents

Torii's latest patents showcase his expertise in converting and processing digital signals. His first patent, titled "Method for converting a digital signal into another digital signal," details a comprehensive conversion method that transforms a first digital signal with a specified sampling period into a second digital signal with a different sampling period. This method comprises four critical steps: oversampling the first digital signal, maintaining the sample value during a brief period corresponding to a common multiple of the two sampling periods, executing an interpolation process, and finally outputting the second digital signal by sampling at the new period.

Another significant patent, "Digital filter capable of sample rate alteration," describes a digital filter that conducts arithmetic operations on input digital data at a predetermined sampling frequency. The invention enhances the sample rate to a frequency that is 'N' times larger than the original, facilitating synchronization and efficient operation control. The filter includes a synchronizing signal generating circuit that detects the original sampling period and generates the necessary synchronizing signal, optimizing the entire process to ensure high performance and reliability.
