(a) Redesign the circuit of Figure 11-32 so that P+ and Q+

Chapter 11, Problem 11.32

(choose chapter or problem)

(a) Redesign the circuit of Figure 11-32 so that \(P^+\) and \(Q^+\) are free of hazards. Use 6 two-input NAND gates and inverters as needed.

(b) Add two outputs, U and V, to your circuit of part (a) so that the values on U and V count the number of times x has changed (0 to 1 and 1 to 0) modulo 4. (U and V will cycle through the values 00, 01, 10, 11, 00, 01, . . . as x changes.) Assume that initially x = 0.
