H3T and H4P. A data sampling system includes a reference signal generator whose frequency is adjusted to be that of the received data, whereby a distortion-free data signal is derived, and a logic arrangement fed with the reference signal, the received signal, and the output distortion-free signal, the logic arrangement producing a signal which adjusts the generator frequency.
