PROCESS AND APPARATUS FOR SYNCHRONIZATION OF DIGITAL SIGNALS

摘要

PROCESS AND APPARATUS FOR SYNCHRONIZATION OF DIGITAL SIGNALS A digital signal formed from successive words representing quantized samples of sound information and comprising silent periods is synchronized with a local reading clock. For that the words are stored in a random access memory as they arrive, they are read at the frequency of the local clock and the filling rate of the store is permanetly determined. A comparator compares this rate with a given range. If the filling rate is greater than a maximum threshold or less than a minimu threshold, the contents of the memory are modified at the first silent interval which appears.
