ALEXANDRIA, Va., July 14 -- United States Patent no. 12,683,756, issued on July 14, was assigned to REALTEK SEMICONDUCTOR Corp. (Hsinchu, Taiwan).

"Falling-edge modulation signal receiver and falling-edge modulation signal sampling method" was invented by Chien-Hsun Lu (Hsinchu, Taiwan) and Chu-King Kung (Hsinchu, Taiwan).

According to the abstract* released by the U.S. Patent & Trademark Office: "A falling-edge modulation signal receiver is configured to process an input signal having a duty cycle varying with a bit value of the input signal. The receiver includes: a phase-locked loop for generating an oversampling clock according to the input signal which correlates with a signal clock, wherein the oversampling frequency is not lower th...
