6. A sequential circuit has two D flip-flops A and B, two inputs x and y, and one output z. The flip-flop equations and circuit are as follows: DA = Ax + B,y Ds = Bx + Ay' Draw the logic diagram of the circuit. Draw a logic diagram of an 8-t0-1 multiplexer with eight 4-bit inputs and three Select signals: 7. control signals: Inputs: 1,-1000 li = 1001 12= 1010 3 1011 14-1100 Is 1101 16 = 1110 17 = 01 1 1 S2 Si So
