Signal processing method

Abstract

A signal processing method is provided. The signal processing method is used in a Gigabit Ethernet system including a device under test (DUT) and a link partner (LP), and includes the following steps. Firstly, an interference detector is configured to detect whether the Gigabit Ethernet system is interfered by other signal sources. Next, a physical layer (PHY) of the DUT or a PHY of the LP is used to, in response to the Gigabit Ethernet system being interfered by the other signal sources, set a request signal indicating whether or not the physical layer enters a low power idle (LPI) mode as FALSE. Which PHY of the DUT and the LP is used to set the request signal indicating whether or not the PHY enters the LPI mode as FALSE depends upon which one of the DUT and the LP is provided with the interference detector.

Dependencies are inferred from the claim text.
