This is an implementation of a Moore machine. I was fiddling around with state machine problems and wanted to simulate a Moore machine. The circuit here has an input, combinational logic, sequential logic, and an output. The output is a function of the the state it is currently at. 

The output is 0 for when the (A,B,C) flip flops are (0,0,0) (0,0,1) (0,1,0). 

The output is 1 for when the (A,B,C) flip flops are (0,1,1) and (1,0,0).

The inputs only determine next state.

As a result, the inputs of the flip flop are functions of the present state. 

This particular state machine is the implementation of the following state table.
