ABSTRACT:
A pitch synchronized helium speech unscrambler is disclosed as including a air of bucket brigade analog delay lines which are timely and rapidly loaded with the electrical signal equivalents of human voice signals that are effectively supplied thereto by a receiving transducer. Said voice signal equivalents are then respectively unloaded more slowly from said pair of bucket brigade delay lines than they were loaded therein by a pair of different frequency clock generators driven in alternate successions by preprogrammed signals divided out from a master oscillator and in synchronism with a predetermined pitch portion of the speech signal received by said receiving transducer. The unloaded signals are then broadcast as acoustical voice signals by a transmitting transducer.
