1. A method comprising:
producing, by a first controller, a waveform based on a counter;
determining, by the first controller, an expected time to receive a synchronization signal;
receiving, by the first controller, the synchronization signal at a time of receipt;
determining, by the first controller, a difference between the expected time and the time of receipt;
applying a first adjustment to the counter to correct a first portion of the difference in a first cycle of the waveform; and
applying a second adjustment to the counter to correct a second portion of the difference in a second cycle of the waveform.
