(25p) Consider the circuit in Figure 4: Draw timing diagrams for the signals a,b,c,d and F after the inputs have switched at time t0 from(x,y,z,w) = (1,1,1,0) to (1,0,1,0). This circuit has a static hazard on c and a dynamic hazard on F. The numbers inside the gate symbols represent gate delays. a Figure 3 b c d e f 0 5 10 20 30 40 50 60 70 80 90 100 110 120 3 4 3 1 3 4 x y z w a b c F d Figure 4....
