In the given sequential circuit if the initial value of Q₁Q₀ = 00, then what…

Starting with the initial state Q1Q0 = 00:

1. First Clock Pulse:

   • Q0 receives the pulse and toggles from 0 to 1.

   • Since Q0 went from 0 to 1 (a positive edge), it triggers Q1.

   • Q1 toggles from 0 to 1.

   • New State: 11

2. Second Clock Pulse:

   • Q0 receives the pulse and toggles from 1 to 0.

   • Since Q0 went from 1 to 0 (a negative edge), it does not trigger the positive edge-triggered Q1.

   • Q1 remains 1.

   • New State: 10

3. Third Clock Pulse:

   1. Q0 receives the pulse and toggles from 0 to 1.

   2. Since Q0 went from 0 to 1 (positive edge), it triggers Q1.

   3. Q1 toggles from 1 to 0.

   4. New State: 01

Final Answer

If the initial value is 00, the next three values of Q1Q0 are:

11, 10, 01
