Abstract
Apparatus for effecting the technique includes a subtraction circuit for producing a difference signal by subtracting successive words of the serial bit stream forming the digital signal. A comparator circuit compares the difference signal to a predetermined maximum slew rate limit signals. If the difference signal is greater than the maximum limit signal, then subtraction and comparison is repeated, after shifting the successive words of the digital signal by one bit. This process is repeated until, when the difference no longer exceeds S, synchronization is assumed.
