ABSTRACT:
A memory system adapted to store samples of a finite portion of a periodic signal and produce an output signal having the same frequency as the periodic signal for a relatively longer time duration. The system includes a network for comparing the initial and terminal portions of the finite portion of the stored signal to determine the relative phase shift therebetween. Portions of the samples of the stored periodic signal and of the phase delayed replicas which extend from the first sample to the next to the last sample thereof are sequentially coupled to an output selectively in accordance with the determined relative phase shift to produce the output signal.
