Information Storage and Retrieval Using Magnetic Cores

Many communications systems use 2-state devices for storage, processing, and multiplexing of information in binary form. Magnetic cores offer an efficient means of storing and processing such information because they need no standby power to hold the information in storage. Three separate but similar circuits are discussed, showing the internal operations of storage and shifting of binary bits in magnetic cores that are used as the memory units in the circuits. A typical application in time-division multiplexing of blocks of binary information is discussed.
