ABSTRACT:
A master and a slave counter have their outputs coupled to an exclusive OR gate which in turn, supplies the D input of a flip-flop. Clock pulses are coupled to the slave counter through an AND gate which is enabled by the Q output of the flip-flop. Clock pulses to the slave counter are inhibited upon occurrence of an output therefrom and until a succeeding output of the master counter occurs, at which time clock pulses are again supplied to both the slave counter and the master counter to synchronize the operation thereof.
