ABSTRACT:
A digital audio signal which is subject to sample-to-sample jitter is synchronised with local reference pulses by the use of a read-write buffer memory. Timing pulses are associated with the input samples. The input samples are applied through a one-sample latch store to the main memory, and the timing pulses are applied by switches either directly or a short delay to the write control input of the main memory. A phase comparator detects sample-by-sample when the write pulses are near to the read pulses and causes the switches to change state in response thereto, and they retain their changed state until a danger of potential read-write contention is again detected when they revert to their original state.
