Title: Kazuaki Wakai: Innovator in Amplitude Modulation Technology
Introduction
Kazuaki Wakai is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of amplitude modulation technology. His innovative approach has led to the development of a unique broadcasting apparatus that enhances audio signal processing.
Latest Patents
Wakai holds a patent for an "Amplitude modulation method and broadcasting apparatus for carrying out." This invention involves an amplitude modulation system where an input analog signal, indicating audio, is converted into a digital form. The low-order bits of the resultant digital signal are then converted back into analog form. This analog signal is utilized to control the gain of an analog controlled amplifier. Additionally, a plurality of digitally controlled amplifiers are selectively turned on or off based on the value of the high-order bits of the digital signal. The carrier amplified by the analog controlled amplifier is combined with carriers amplified by the digitally controlled amplifiers. This system provides comparatively rough amplitude constituents from the outputs of the digitally controlled amplifiers and comparatively fine amplitude constituents from the output of the analog controlled amplifier. Wakai's innovative work has resulted in 1 patent.
