ABSTRACT:
The invention discloses baseline wandering correction techniques. A baseline wandering correction device comprises a differentiator differentiating a data signal to generate a differentiated signal, a operation signal coupling to the differentiator and proceeding with an operation based on the data signal according to the differentiated signal to generate an operated signal, an extracting module coupling to the operation module and determining a first and a second threshold value according to the operated signal, a comparing signal coupling to the extracting module and comparing the operated signal with the first and second threshold values to generate a first and a second processing signal, and a latch module latching the first and second processing signals to generate an output signal.
