1. Construct a Moore Machine that counts modulo 3 (that is, 0 1 2 0 1 2 ) and Design the circuit using D flip-flops to implement the mod-3 counter

2.

A Mux-Not flip-flop (MN flip-flop) behaves as follows: If M = 1, the flip-flop complements the current state. If M = 0, the next state of the flip-flop is equal to the value of N.

a) Derive the characteristic table for the flip-flop.

b) Show how a JK flip-flop can be converted to a MN flip-flop by adding gate(s) and

inverter(s).
