REMOVAL OF SWITCHING DISCONTINUITY IN A HYBRID SWITCHED MODE AMPLIFIER

WIPO Patent Application WO/2017/160520

A3

A signal processing system for producing a load voltage at a load output of the signal processing system, wherein the load output comprises a first load terminal having a first load voltage and a second load terminal having a second load voltage such that the load voltage comprises a difference between the first load voltage and the second load voltage, and may include a first processing path configured to process a first signal derived from an input signal to generate the first load voltage at a first processing path output, a second processing path configured to process a second signal received at a second processing path input and derived from the input signal, wherein the second signal comprises information of the input signal absent from the first signal, to generate the second load voltage at a second processing path output, and a high-pass filter coupled between the first processing path output and the second processing path input.
