Simple Algorithm for Sampling Synchronization of ADCs

This paper describes a simple and easy to implement algorithm for synchronizing analog-to-digital converters to the fundamental of a continuous periodic signal. It is based on the discrete-Fourier transform (DFT) on sampled data and uses DFT- leakage detection to ensure a synchronous sampling. It may be applied to distorted waveforms in general, irrespective of the type of ADC used, and no windowing functions on sampled data need to be applied.
