  • Automatic cable balancing network
    Patent number: 3982080
    Abstract: Disclosed is apparatus for automatically balancing the hybrid network in a telephone system having a bidirectional cable connected to a first preselected hybrid network port and a balancing network connected to a second preselected hybrid network port. In response to a test signal applied to a third port of the hybrid network, the disclosed apparatus develops control signals in response to the magnitude and phase of signals at the hybrid network's first and second ports. These signals adjust the impedance of the balancing network to effect hybrid network balance.
