Latest Patents

Wei-Chiang Hsu holds a patent for an "Echo cancelling system and echo cancelling method." This invention involves a digital-to-analog converter circuit that generates an analog transmitted signal based on a digital transmitted signal. A first echo canceller circuit produces a first echo cancelling signal according to the digital transmitted signal. A processor circuit then generates an analog processed signal based on the analog transmitted signal, the first echo cancelling signal, and a received signal. Additionally, an analog-to-digital converter circuit generates a digital value based on the analog processed signal and two slicer levels from a plurality of slicer levels. A storage circuit maintains a look-up table that records an offset value corresponding to the digital value. This offset value is updated according to an error value associated with the first output signal.
