Using necessary logic gates and D-type flip-flops, create a sequential circuit (one input–one output) from the state table given below.


Notice that when I = 0 the output state does not change such that Qn+1 = Qn = 0. In other words, I acts as an enable input. When the circuit is enabled (I = 1) the output toggles between 0 and 1. An AND gate is ideal for creating an ENABLE input. See the circuit diagram here and notice that the inputs to the AND gate are I and the inverted output of the D flip-flop; thus, the toggling result indicated in the table.
