Digital Electronic Question Paper

1) Design a Asynchronous mod N Asynchronous Counter by skipping of state a)000 ------> 010 b)000 -------> 101 c)000 --------> 100 1.1)Show the design steps:

1.2)Then test the inputs (clock) shown below

1.3)Please write down the counting sequence Q2 Q1

Q0

1.4)Draw State Transition Diagram for this experiment

1.5)hat is the difference between the counting sequence of an up and a down counter?

1.6)What is the advantage of a synchronous counter over an asynchronous counter? What is the disadvantage?
