I hope this is the place to ask such a question.
Given a shift register- within 8 clock pulses 8 bits will enter this register, I need to make a circuit with this register, and other 3 flip-flops such that its exit line would be 1 if the first 4 bits are equal to the last 4.
This is an example of possible solution.
My question for you is: How come that only at the end of the 8th pulse a value would go out to the "equal" line? (or that in this solution- successes consider as output of "1111"?)
