  • Patent number: 4087626
    Abstract: Serial data is scrambled at a transmitting terminal by storing it in sequential locations in a first random access memory, while previously stored information is read out of a second random access memory using a pseudo-random address counter. Whenever one memory is filled and the other memory is emptied, the roles of the memories are transposed. Similar apparatus at a receiving terminal is operated in synchronism and phase to unscramble the received data.
