Abstract
A decoder-encoder with a biphase or delta-distance to binary decoding circuit adapts the data sampling interval to compensate for a non-centered signal level transition in the preceding sample interval. The location of the signal level transition in the prior sampling interval modifies the location of the subsequent sampling interval. The adaptive sampling maintains relative frequency and phase synchronization between the biphase or delta-distance source and the decoding circuit.
