2. Design a digital circuit, using a decoder, only Nor gates, a 7-segment display, and D Flip Flops, that repeatedly outputs the sequences of characters ‘P’, ‘E’, ‘A’, ‘L’ if x=0 and ‘L’, ‘E’, ‘A’, ‘P’ if x=1 .
The output expressions Y1 and Y0 have same variations equal to Q1 and Q0
So Y1=Q1 , Y0=Q0 ;
The sequence FSM output to seven segment decoder conversion
