Abstract
A data transmission system receiver comprising a data synchronisation unit and first-in first-out data store connected in parallel to receive incoming data signals, in which the data store delays the incoming data signals by a time period which corresponds to the time required for the synchronisation unit to achieve synchronisation of a clock with the incoming data signals and in which data gate or sampler means responsive to signals from the synchronisation unit indicating that synchronisation has been achieved enables data signals to be passed from the store to a data line.
