Abstract

PURPOSE:To directly lower the loss of the signal and automatically deal with the change of impedance in two line passage by using the active filter, digital filter and the like. CONSTITUTION:The input signal put into through the amplifier 15 from the four line passage 4 is supplied to two line passage 1 through the operated element 9, while it is transmitted to the input terminal (+) of the subtraction circuit 11. The transmitted signal B transmitted from the two line passage reaches the input terminal (+) of the subtraction circuit 11 through the operated adding circuit 8. If the transmission property of the variable transmission circuit 10 is set at Z0/(Z0+Z1) (In this case, Z0, Z1 are impedance of the two line passage 1 and the element 9), the output of the detraction circuit is Z1B/(Z0+Z1) and the direct loss of the receiving signal can be minimized.
