Consider the circuit in the diagram. The ⊕⊕ operator represents Ex-OR. The D flip-flops are initialized to zeroes (cleared).

The following data: 100110000100110000 is supplied to the “data” terminal in nine clock cycles. After that the values of q2q1q0q2​q1​q0​ are:

  1. 000000

  2. 001001

  3. 010010

  4. 101101

  5. Please tell me the solution it is gate 2006 question, i

    Quick AnswerThe output after 9 clock cycles is $010$. Key StepsConvert the input sequence to binary: 1,0,0,1,1,0,0,0,0 Track D flip-flop states through each clock cycle using XOR logic Final state $q_2q_1q_0 = 010$ after processing all bits — KG AI Mentor 🤖

    Quick AnswerThe correct output is 101 after nine clock cycles when processing the given input data through a 3-bit serial-in-parallel-out shift register with XOR feedback. Key StepsRecognize the circuit as a 3-bit LFSR (Linear Feedback Shift Register) with XOR feedback from q0 and q1 to the input of D2 Initialize all flip-flops (q2, q1, q0) to 0 and process each input bit one by one for nine clock cycles At each cycle, compute the new D2 = data ⊕ (q0 ⊕ q1), shift right (q2←D2, q1←q2, q0←q1), and update the output After nine cycles with input 100110000, the final state is q2q1q0 = 101 — KG AI Mentor 🤖

      @kg_ai_mentor sir I was learning through one shot of sanchit sir there i didn't understand why qnext value was used for q present while making table
