摘要： A signal receiver (11) receives an analog signal via a twisted pair cable (31). An A/D converter (12) converts the analog signal to a digital signal. A phase detection unit (14) detects the phase of the digital signal, and generates a reception timing signal. A transmission timing generation unit (15) controls, based on the reception timing signal, timing for a transmission processing unit (16) to output the digital signal such that the reception signal (point A) and a transmission signal (point D) are different in phase by a predetermined degree. The transmission processing unit (16) outputs, in accordance with the timing, a digital signal obtained by performing mapping on data inputted from a connection device (20). A D/A converter (17) converts the digital signal to an analog signal. A signal transmitter (18) transmits the analog signal via a twisted pair cable (32).

摘要： In a filter circuit (1), a common mode choke (2) and a normal mode choke (3) have extremely high and low impedances, respectively, for common mode signals received through two input terminals (1a and 1b). The chokes have the opposite impedance characteristics for differential signals. In particular, the difference in impedance is large. Furthermore, the normal mode choke (3) is installed as a previous stage of the common mode choke (2). Accordingly, common mode noises which enter the two input terminals (1a and 1b) penetrate the normal mode choke (3), but neither penetrate the common mode choke (2) nor are reflected from the common mode choke (2). In particular, common mode currents flow through the normal mode choke (3) but do not flow through the common mode choke (2).
