• The FF#4 flip-flop operates normally and changes its state on the Blank 1 of the clock pulse
• In FF#4, the asynchronous inputs (SR) sets/clears the flip-flop when they are in Blank 2 state.
• If D=1, S=0, R = 0, then FF#4 goes to Blank 3state on the active edge of the clock pulse.
• The FF#4 flip-flop operates normally and changes its state on the active edge of the clock pulse, when both S and R are in Blank 4state.
• If D=1, S=0, R = 1, then FF#1 goes to Blank 5 state regardless of the clock pulse and the value of D input.
• To set the flop FF#4, you have to make the asynchronous inputs SR= Blank 6
