Using D flip-flops, design a sequential circuit that detects 3 consecutive 0s in a bit stream. A continuous bit stream is fed at the input of the circuit. Every time the circuit detects the sequence 000, an output line is made HIGH. a) Sketch the state diagram b) Tabulate the state table c) Using K-maps, write down the simplified Boolean expressions of the flip-flops input equations d) Sketch the logic diagram
