NASA NTRS1968

Self-correcting, synchronizing ring counter using integrated circuit devices

Three nand gate circuits are used to add error detection and reset logic circuitry for initiating and retaining the correct binary state in the flip-flop circuits of a ring counter. As the input signals are counted, the position of the specified state moves in ordered sequence around circuit loop.
