Abstract: An encoder and a signal processing method are disclosed. The method includes: receiving an analog signal, and generating a filtered analog signal by an analog filter according to the input signal and a first frequency indication signal; generating a digital signal by an analog-to-digital converter according to the filtered analog signal; generating a filtered digital signal by a digital filter according to the digital signal and a second frequency indication signal; generating a seventh signal and an eighth signal by a dynamic offset calibration unit according to the filtered digital signal and a period indication signal; and generating a position information by a position detection unit according to the seventh signal and the eighth signal. The first frequency indication signal, the second frequency indication signal and the period indication signal are generated by a frequency generation module according to the filtered analog signal or the digital signal.

Abstract: In an embodiment, a power apparatus operating method includes receiving a mode switching signal to control an operating of a power apparatus to provide and/or receive a preconfigured load; sensing an enable route current of an enable route, and a bypass route current of a bypass route, wherein the enable route current flowing through a battery module including one or more batteries, and the bypass route current does not flowing through the battery module; and controlling driving a first and a second switches by using a negative feedback control and an open loop control, to perform a current switching between an enable mode and a bypass mode of the power apparatus, based on the mode switching signal, the enable route current and the bypass route current, wherein the enable mode uses the power apparatus and the bypass mode bypasses the power apparatus.
