ABSTRACT:
In a message signal scrambling apparatus, the signal is divided into elements, each of one time slot duration, and the elements are re-arranged in order so as to produce a signal scrambled in time. Each element is entered and stored in a charge coupled device, from which is extracted as required to form part of a re-arranged order of elements.
