Abstract: In one embodiment, a medical system includes a catheter interface comprising electrode lines configured to be electrically connected to respective electrodes of a catheter, and a signal generation apparatus configured to generate signal pulses, each of the signal pulses comprising a carrier frequency and having a non-rectangular signal envelope, the signal generation apparatus being configured to time multiplex the signal pulses among the electrode lines.

Abstract: A power line interference (PLI) suppression method includes receiving an input analog signal superimposed with PLI, and digitally estimating one or more harmonics of the PLI in real-time. Responsively to the one or more digitally estimated harmonics, one or more analog harmonic waveforms are outputted, that match the respective one or more harmonics of the PLI. The input analog signal and the one or more analog harmonic waveforms are received, and the superimposed PLI in the input analog signal is suppressed using the one or more analog harmonic waveforms. An analog output signal is outputted, that corresponds to the input analog signal having the suppressed PLI.
