SYNCHRONOUS BINARY COUNTER UTILIZING A PIPELINE TOGGLE SIGNAL PROPAGATION TECHNIQUE

摘要

A synchronous binary counter includes a plurality of counter stages wherein each stage experiences a state change in response to the application of a toggle signal thereto, Gating apparatus is provided between successive ones of the counter stages and said gating apparatus is responsive to a first state of the preceding counter stage for transferring the toggle signal to successive ones of the counter stages and responsive to a second state of the preceding counter stage for blocking the transfer of the toggle signal. The apparatus grounds a toggle signal input to each counter stage in response to a clock signal being applied.
