Title: The Innovations of Dan Q Tu
Introduction
Dan Q Tu is a notable inventor based in San Diego, CA. He holds a total of 4 patents that showcase his expertise in processing signals and improving technology. His work has significantly contributed to advancements in the field of communications.
Latest Patents
One of Dan Q Tu's latest patents is focused on the simultaneous tuning of multiple channels using intermediate frequency sub-sampling. This method involves processing a single sub-channel that includes two or more combined channels. By utilizing intermediate frequency sub-sampling, multiple channels from a broad band signal are combined into a single sub-channel for further analog and digital processing. Each channel is down converted to an intermediate frequency, filtered to eliminate undesired channels, and combined so that they are adjacent to each other. A digital representation of the sub-channel is then produced from the combined intermediate frequency channels. Each channel within this digital representation is down converted to baseband, and the in-phase and quadrature components are separated. This innovative approach may reduce the number of analog to digital converters and control amplifiers used in analog processing by a factor of four compared to traditional direct down conversion techniques.
