  • Four wire to two wire converter
    Patent number: 4387277
    Abstract: The connecting device according to the present invention comprises for a two wire to four wire converter which connects the reception channel of a private network to the public network via an amplifier, whose symmetrical outputs are connected to the public network by capacitors, the gain loss due to these capacitors being compensated by a second amplifier. For the transmission channel a third amplifier has inputs connected to the public network by capacitors and an output connected to one input of a fourth amplifier, whose other input is connected by a phase shifting network to the reception channel.
