Abstract:
1. A method for compensating a baseline wander of a transmission signal, the transmission signal comprising a plurality of first pulses and a plurality of second pulses for representing digital data coded in the transmission signal; the method comprising: (a)generating an accumulation result according to a number of the first pulses and a number of the second pulses for estimating the baseline wander of the transmission signal; and (b)compensating the baseline wander of the transmission line according to the accumulation result; wherein when the number of the first pulses is increased by one, the accumulation result is increased by a first weighted value accordingly, and when the number of the second pulses is increased by one, the accumulation result is decreased by a second weighted value accordingly; wherein when a voltage level of the transmission signal is greater than a first threshold value, the first weighted value is decreased, and when the voltage level of the transmission signal is less than a second threshold value, the first weighted value is increased; wherein when the voltage level of the transmission signal is greater than the first threshold value, the second weighted value is increased, and when the voltage level of the transmission signal is less than the second threshold value, the second weighted value is decreased.
