A four bit right shift register is shifting the data to the right for every clock pulse. The circuit diagram is:

 

The initial loaded with binary stream 0011 as Q₀, Q₁, Q₂ and Q₃ respectively. Which clock pulse is responsible for highest decimal data to be stored in the shift register?

In Johnson’s counter, all the positive triggered JK flip-flops are used. Initially, all the flip-flops are Q₂ Q₁ Q₀ = 000. Which of the following statements is/are true?

Consider the circuit of J-K flip-flops as given below:

The above circuit shows mod-P counter here P is equal to ____.

Consider the circuit given below:

Suppose the initial value of Q₁Q₂Q₃ is 001. What is the value of Q₁Q₂Q₃ after four clock pulses? (Note- If the value of Q₁ is 0, Q₂ is 0, and Q₃ is 1, then the answer will be 001)

Let us have three identical modulo-5 counters. What is the overall modulo of this circuit?
