#$%^&*AU2014271324C120160616.pdf#####SYSTEMS AND METHODS FOR MULTIFREQUENCY CABLE COMPENSATION ABSTRACT The electrosurgical systems and methods of the present disclosure perform cable compensation using an electrosurgical generator (102) that includes a plurality of sensors (230) configured to sense voltage and current waveforms, a plurality of medium-band filters, a plurality of narrowband filters, and a signal processor (250). The plurality of medium-band filters and narrowband filters pass sensed voltage and current waveforms at a plurality of predetermined frequencies. The signal processor (250) calculates medium-band RMS voltage and current values using the output from the plurality of medium-band filters, calculates narrowband phase and magnitude values using the output from the plurality of narrowband filters, calculates tissue impedance based on the medium-band RMS voltage and current values and the narrowband phase value, and generates a control signal to control the energy generated by the electrosurgical generator (102) based on the calculated tissue impedance. 9454019 1
