Hi lostinxlation,
To clarify question3, when we use a binary ripple counter, and denote the output as A3A2A1A0. then the timeperiod of A0 is twice that of the clock. That of A1 is 4times that of clock. So we need to design a ckt that produces an output that has time period 3 times that of clock.
Question 4, setup, hold time and propagation dealy is given, we have to calculate the max frequency of the clock that can be aplplied.
Also could tell me where I could get similar questions.
Thanks a lot,
