1. A device for estimating the termination to a wired transmission-line carrying a signal in a first frequency band, the device comprising:

  • a port for connecting to one end of the wired transmission-line,an energy transmitter coupled to said port for transmitting energy to the wired transmission-line, the energy being in a second frequency band distinct and separate from the first frequency band, while the signal in the first frequency band is being carried simultaneously with the energy in the second frequency band by the wired transmission-line, andan impedance measuring unit coupled to the one end of the transmission-line for instantaneously measuring the characteristic impedance Z of the transmission-line on the basis of the energy in the second frequency band, wherein the optimal termination value of the transmission-line is estimated based on the measured value Z.
