His innovative work has led to the development of a unique apparatus that enhances the quality of digital signal transmission.

Latest Patents

Kawataka holds 1 patent for his invention titled "Serial Digital Signal Transmission Apparatus." This apparatus is designed to transmit HDTV digital serial signals with minimal jitter by utilizing the SRTS method. The technology involves counting parallel clocks with an N counter, which are then supplied to a latch circuit. The output count of a p-bit counter is latched, and the resulting RTSs are compared and supplied to a phase-locked loop (PLL) circuit. This process multiplies the clocks by N, allowing for the regeneration of parallel clocks at frequencies of 74.25 MHz or 74.25/1.001 MHz. The transmitted data undergoes parallel-to-serial conversion using a PS converter, ensuring high-quality signal transmission.

Career Highlights

Kawataka is currently employed at NEC Corporation, where he continues to work on advancements in digital signal technology. His expertise in this area has positioned him as a key figure in the development of innovative solutions for modern communication systems.
