A finite state machine (FSM) is implemented using the D flip-flops A and B, and logic gates, as shown in the figure below. The four possible states of the FSM are QAQB =
![Finite state machines Problem 1. (Katz, problem 8.13) A finite state machine has one input and one output. The output becomes 1 and remains 1 thereafter when at least two 0's and two 1's have occurred as inputs, regardless of the order of appearance ... Finite state machines Problem 1.
