Latest Patents
One of his latest patents is a digital communication system using partial response and bipolar coding. This system includes a transmitter with a (1,0) precoder that precodes a unipolar input digital data stream. The output signal is converted into a bipolar signal, which is then transmitted through a metallic transmission line to a receiver. The receiver features a digitizer and a line equalization filter to address losses during signal propagation. Additionally, a (1,1) converter and a clock recovery circuit are included to reconstruct the original digital data stream.
Another notable patent is the rate conversion digital filter. This finite impulse response digital filter utilizes selectors to alternately choose samples from two data streams. It incorporates subfilters that introduce different incremental delay times to the outputs, enhancing the processing of the signals.
