The circuit presented here makes amplitude modulation possible, and it also has the significant advantage that it replaces the somewhat exotic and quite expensive OP603AP output opamp with a standard ...
Abstract: This paper presents a novel flat-top directional modulation (DM) synthesis approach utilizing constant amplitude antenna arrays. Unlike traditional modulation schemes, the proposed method ...
Abstract: This study proposes a method to present pure low-frequency vibration sensations to the face that cannot be presented by small commercially available vibrators. The core innovation lies in ...
