Latest Patents
One of Ward's latest patents is titled "Direct power output digital to analog conversion of digital audio signals." This invention operates to directly convert digital audio signals into an analog power audio output signal capable of driving a speaker, eliminating the need for further amplification or modification. The technology incorporates a digital-to-analog converter within the same feedback circuit as a current-to-voltage power amplifier, utilizing a single resistive feedback network to supply the feedback signal from the output terminal of the amplifier to the summing junction.
Another notable patent is the "Method and system for time domain interpolation of digital audio signals." This method allows a digital audio system to reconstruct a digital audio signal using time domain interpolation and direct power digital-to-analog conversion. A signal processor performs the time domain interpolation on the original digital audio signal, enabling the precise recreation of the original audio. The direct power output digital-to-analog converter then generates an analog power audio output signal from the interpolated digital audio signal, allowing for direct speaker drive without the need for further amplification.
