2) A synchronous sequential circuit which gives 1 at its 1-bit output when the last three values of its 2-bit input are 10-10-11 will be designed. D type flip-flops, 4-to-16 active 1 output DECODERs and OR gates will be used for implementation. (Y=D) a) Draw the Mealy type state diagram of the circuit. Draw the Moore type state diagram of the circuit. c) Draw the state table for the diagram in (a). d) Drive the flip-flop input and output Boolean functions. e) Draw the circuit b)
