Question

(34) If a flip-flop has a "Preset" input marked with an inversion circle, applying a HI signal to this input will (a ke the output of the flip-flop go HI (b) make the output of the flip-flop go LO always make the output toggle (d have no effect on the output of the flip-flop Questions 35 through 36 deal with the circuit below: (35) If A changes from 1 to O, B will be (a) definitely (b) definitely 1 (c uncertain (depends on the power-on state and signal histories) (36) IfB-1 while C changes state from 1 to 0, X wil (a) become (or remain) 0 (b) become (or remain) 1 (c remain unchanged (regardless of whether the initial value is 0 or 1)
