QUESTION 36 Whose operations are more faster among the following? O 1. Combinational circuits 2. Flip-flops -Latches Sequential circuits 4. QUESTION 37 Which of the following describes the operation of a positive edge-triggered D flip-flop? O If both inputs are HIGH, the output will toggle The output will follow the input on the leading edge of the clock O When both inputs are LOW, an invalid state exists The input is toggled into the flip-flop on the leading edge of the clock and is passed to the output on the trailing edge of the clock QUESTION 38 How many stable states a combinational circuits have? 3 O 4 425 QUESTION 39 A negative-edge-triggered flip-flop transfers data from input to output on the Leading O Trailing Level Other edge of the clock pulse.
