ABSTRACT
In Topic 21 we showed how a data-type (or D-type) flip-flop could be connected to make it into a toggletype (or T-type) flip-flop. This is simply done by connecting its Q output to its D input. As a T-type flip-flop, its output changes state whenever its clock (or C) input changes from low to high — that is, it is triggered on a rising edge.
