Latest Patents
One of Harada's latest patents is a noise reduction method and apparatus. This invention focuses on reducing noise that overlaps detected signals in a common frequency band. The method involves decomposing an input signal into a noise-free part, known as the basic signal, and a noise-overlapping part called the residual signal. By comparing the residual signal with a computed comparison signal, Harada's method effectively reduces signal-overlapping noise while maintaining the integrity of the original signal.
Another notable patent is a sampling method and circuit designed for high-fidelity sampling of input waveform signals. This invention detects peak and bottom values during each sampling period, holding these values to ensure accurate representation of the input waveform. The method allows for the generation of sampling values based on the operational state of the peak or bottom hold, ensuring that the output reflects the most recent signal levels.
