Latest Patents

Zukui Song's latest patents include innovative methods for digital adaptive feedforward harmonic distortion compensation. One patent describes a system and method to compress digital video based on human factors expressed as a desirability score. This method involves passing a digital input signal through a pulse-width modulator and subsequently through a power switching device. The output of this device consists of a series of pulses. The process includes receiving the output at a comparator and determining a net signal based on the comparator's output. A timing error signal is then generated to adjust the digital input signal, compensating for harmonic distortion. Another patent focuses on a digital timing read-back and an adaptive feedforward compensation algorithm aimed at reducing harmonic distortion. This approach generates harmonic components digitally, which are added to the input signal to counteract the output harmonic distortion.
