  • Circuitry for simultaneous transmission of signals and power
    Patent number: 4017845
    Abstract: A transmission line having a pair of wires enclosed in a shield is used to simultaneously transmit high frequency signals and low frequency power between distant locations. At the sending end of the line a high frequency source is connected between the first and second wires by circuitry which prevents the low frequency power from being coupled into the high frequency source. A low frequency power supply is connected between the shield and both of the wires by circuitry which prevents the high frequency signals from being coupled into the low frequency supply. At the receiving end of the transmission line circuitry is provided which separates the high frequency signals from the low frequency power.
