E1: A circuit-based apparatus comprises a transceiver circuit configured and arranged to communicate over power distribution lines that carry power using alternating current (AC).
E2: A circuit-based apparatus comprises one or more processing circuits configured and arranged to provide an analog to digital converter module configured to generate an input digital signal from an analog signal that was received at the transceiver circuit.
E3: A circuit-based apparatus comprises a decimator module configured to produce, in response to a variable decimation rate, a decimated input digital signal; A reference signal generator module configured to generate a reference signal having a frequency responsive to the decimation rate.
E4: A decimation modification module configured and arranged to modify, in response to an indication of change in a phase difference between the reference signal and the AC, the decimation rate to counteract the phase difference.
