US 2026/0025619 A1 · SIGNAL PROCESSING SYSTEM AND SIGNAL PROCESSING METHOD

Abstract

A signal processing system and a signal processing method are provided. The signal processing method includes: in response to that a mode selection element receives a turn-off signal, outputting a first signal by the mode selection element; in response to that a switching element receives the first signal, switching from outputting a digital source signal to outputting a virtual signal by the switching element; in response to that a first delay element receives the first signal, outputting a first delay signal by the first delay element, where the first delay signal reaches a first voltage after a first delay time; and in response to that the first delay signal reaches the first voltage, stop outputting an output voltage by a power element.

Dependent claims

A signal processing system comprising:

a mode selection element configured to execute, in response to receiving a turn-off signal, outputting a first signal;
a switching element coupled to the mode selection element, wherein the switching element is configured to, in response to receiving the first signal, switch from outputting a digital source signal to outputting a virtual signal;
a first delay element coupled to the mode selection element, wherein the first delay element is configured to, in response to receiving the first signal, output a first delay signal, wherein the first delay signal reaches a first voltage after a first delay time;
and
a power element coupled to the first delay element, wherein the power element is configured to, in response to that the first delay signal reaches the first voltages, stop outputting an output voltage.
