The second switch(202) selects one of the forward signal selected by the first switch(201) and a reverse signal transferred through the fourth switch(205). A filter/amplifier(203) filters the forward and reverse signals selected by the second switch(202), amplifies them, and controls their gain. The third switch(204) selects a forward direction or a reverse direction in order to transmit an output signal of the filter/amplifier(203).
