ABSTRACT:
A scrambler system is provided for the detection and separation of synchronization signals from data signals, and for the scrambling of the data signals such that no long and repeatable series of one's or zero's are present in the data stream. The scrambler provides an exclusive OR operation to a pseudo random number sequence and the data signals prior to their modulation and transmission. At the receiving end, the identical pseudo random sequence is exclusive OR'ed with the demodulated data, causing the data to be restored to its original form. Thus, an undesirable continuous stream of ones or zeros is eliminated by the scrambler prior to its transmission.
