A method of decoding digital synchronizing signals each of which consists of a plurality of bits in a predetermined pattern, the intervals between the starts of successive synchronizing signals in an input digital signal being variable over a range, comprises ascertaining the bit period distance between the starts of two successive synchronizing signals, subsequently searching the input digital signal for the pattern using a window comprising the bit period distance, which window is varied in position if the bit period distance changes, and supplying an output synchronizing pulse in synchronism with subsequent synchronizing signals found in the window. |
