Question

Q3. Using the circuit below, assume all inputs A, B and C are from a 3-bit up counter. Output Y must go HIGH (logic 1) for when A, B and C inputs are in a set sequence. (a) Find the sequence that will make Y go HIGH. (b) Explain why the START pulse is needed.

Step 1

Looking at the circuit, we can see that there are two D flip-flops connected in series. The output of the first flip-flop (Q1) is connected to the input of the second flip-flop (D2). The output of the second flip-flop (Q2) is connected to the input of an AND gate Show more…
