Title: Masatoshi Nishina: Innovator in Signal Processing Technology
Introduction
Masatoshi Nishina is a prominent inventor based in Kanagawa-ken, Japan. He has made significant contributions to the field of signal processing, particularly in the development of disk devices. With a total of 8 patents to his name, Nishina's work has had a lasting impact on technology.
Latest Patents
One of his latest patents focuses on a disk device and method of generating a signal representing the head. This innovative signal processing device features analog-to-digital conversion of a burst signal. It includes a mechanism for selecting a data bus to notify a disk control device of the conversion result via an NRZ data bus. The disk control device is equipped with means for storing the results of the analog-to-digital conversion of the servo positional signal. The positional signal of the disk device's head is digitized in an R/W channel. Sampling for digital conversion occurs only within a defined window near the peaks of the positional signal. The values obtained from sampling the peaks are averaged by an averaging circuit, effectively eliminating the influence of noise outside the window. Although noise within the window is sampled, its adverse effects are minimized through the averaging process.
