In a transmission system using a signal-phase shift to encode data, the clock for sampling of the signal for data recovery is maintained in phase with the transmitter clock by a detector which indicates the signal positions having the same voltage magnitudes at positions 90.degree. apart in the signal cycle. The sampling clock is controlled to sample the signal at the indicated points thereby enabling other devices to translate the transmitted data.
