Data transmission using switched resonance

An arrangement for the transmission of binary data via electrical conductors, said arrangement including inductance, capacitance, an electronic switching device and a regenerative energy replacement circuit, said electronic switching device being in series with said inductance and in parallel with said capacitance, said capacitance being in parallel with said conductors, said capacitance and inductance forming a switched resonant circuit, said electronic switching device adapted to be switched on to permit current flow through said inductance until the charge on said capacitance has changed sign and returned to approximately the same magnitude present before switching on said electronic switching device, thus creating a reversal of the data state signalled via electronic conductors, after which point in time said electronic switching device is switched off until the next change of data state requiring to be signalled and said regenerative energy replacement circuit replacing any loss of charge due to losses occurring in any of the elements forming said arrangement, whereby the state of said binary data is represented by the polarity of the voltage between said electrical conductors.
