Abstract
1,138,693. Delay stores. PATELHOLD PATENTVERWERTUNGS & ELECTROHOLDING A.G. 24 Feb., 1966 [26 Feb., 1965], No. 8267/66. Heading G4C. [Also in Divisions H3 and H4] A delay store comprises an input line 1 having an analogue signal D n which is converted to digital form at AD. The resultant signal is stored at LD1 by capacitors or cores and readout to line 2 by way of digital-to-analogue converter DA 1 . The digital signal also passes to a second store LD 2 , whose output is converted to analogue form for line 3 by DA 2 .
