1. A circuit comprising:

  • a line driver configured and arranged to couple data-carrying symbols over a power line, via a waveform, that carries an alternating current signal having a frequency or phase that varies, relative to a frequency or phase of previous cycles of the alternating current signal, the data-carrying symbols corresponding to respective information signals;

    a signal-monitoring circuit configured and arranged for monitoring variations in the alternating current signal;

    an encoding circuit configured and arranged to provide encoded parameters that define, at least in part, data useful for providing steps of the waveform to account for the variations; and

    a logic circuit configured and arranged to respond to the encoding circuit by feeding the line driver with stepped data that is processed for modulating the alternating current signal of the power line with the data-carrying symbols.
