  • Scrambler speech transmission and synchronization system
    Patent number: 4268720
    Abstract: A system is provided for time segment scrambling speech encoding, wherein an internal key code is provided for control thereof. The scrambling and reset units are synchronized by start and reset clock pulses. The scrambling unit can also scramble individual segments by an inversion process in accordance with a second internal key code, such as, for example, time inversion and frequency inversion. A related system for unscrambling scrambled speech transmission and synchronization therefore is set forth as another embodiment of the invention.
