Sampling and measuring a periodic signal is disclosed. A periodic signal is sampled. The sampling frequency is less than the Nyquist rate of the periodic signal. A period of the periodic signal is determined. A phase of the periodic signal is tracked to determine a sample's position on the period of the periodic signal. A replica of the periodic signal is reconstructed. A measurement of the periodic signal is determined based on a measurement of the replica of the periodic signal.
