Design a Mealy sequence detector that has one input (x) and one output (z). The circuit examines groups of four consecutive bits and produces an output z = 1 if the input sequence 0111 or 1011 occurs. The circuit resets after every four inputs. Complete the table shown below and use the process of state equivalency and row matching to reduce the table to seven states. Draw the state diagram and realize the circuit using one-hot state assignment and D flip-flops
