Abstract
The present disclosure illustrates a baseline wander compensating method adapted for compensating baseline wander induced in an Ethernet transceiver. The baseline wander compensating method comprises following steps. Firstly, an output packet is detected. Next, a detection result of the output packet and a predetermined value are compared, and a control signal is generated correspondingly. Based on the control signal, a first calibration signal or a second calibration signal is selected, and a calibrating calculation is executed for the selected one of the first calibration signal and a second calibration signal. Next, an input signal is compensated according to a baseline calibration value generated from the calibrating calculation.
