Abstract

The ring or commutator circuit utilizes n latches and 2n logic circuits. The ring has an even number of positions with a minimum of six, uses standard type logic, uses no trigger, and is simple in structure and fast with respect to the logic type used.

Ring Circuit

The ring or commutator circuit utilizes n latches and 2n logic circuits. The ring has an even number of positions with a minimum of six, uses standard type logic, uses no trigger, and is simple in structure and fast with respect to the logic type used.

The latches are numbered L1... Ln. The AND outputs are identified as R1... Rn for the first half of the AND circuits and R(n+1)... R(2n-1), R2n for the second half. Shift or advance pulses K are applied to every other AND circuit while K is applied to the alternate set. NOR circuits may also be used in place of the AND circuits.

The basic operation of the ring is that the latches turn on one at a time as the first half of the AND circuits advances. The latches are turned off one at a time as the ring advances through the second half of the AND circuits. In a starting position, all the latches are off, K is on and only output R2n is on. To effect the first advance, K comes on, turning off R2n. R1 is properly conditioned and turns on, consequently turning on L1. Other advances work in a similar manner.
