2. A set-dominant flip-flop has set and reset inputs. It differs from a conventional SR flip-flop in that, when both S and R are equal to 1 , the flip-flop is set. (i) Obtain the characteristic table of the set-dominant flip-flop. (ii) Derive the excitation table for the set-dominant flip-flop. (iii) Design a positive-edge triggered set-dominant flip-flop using D-FF. (iv) Design a positive-edge triggered set-dominant flip-flop using JK-FF. 2.
