Patent ID: 7227451

Claim:
A method for dynamically tuning a power line communication system comprising an inductive coupler, a tank circuit comprising a plurality of capacitors, a first transmitter, and a receiver, said method comprising: passing a first selected carrier frequency signal generated by said first transmitter through said coupler; receiving said first selected carrier frequency signal at said receiver; measuring amplitude of said received first selected carrier frequency signal; switching said capacitors in and out of said tank circuit until said measured amplitude of said received first selected carrier frequency signal is at a maximum; passing a second selected carrier frequency signal generated by said first transmitter through said coupler; receiving said second selected carrier frequency signal at said receiver; measuring amplitude of said received second selected carrier frequency signal; and switching said capacitors in and out of said tank circuit until said measured amplitude of said received second selected carrier frequency signal is at a maximum; wherein said second selected carrier frequency signal is different from said first selected carrier frequency signal.
