Exercise
1 Consider a 2-bit UP/DOWN synchronous counters that count in the sequence 00, 01,10, 11,
00,01,11,10,01. Draw its logic circuit and the operation time diagram

2 Show the difference(s) between an up counter and a down counter by using: (i) their respective logic
circuit diagrams, (ii) their respective time diagrams

3 The counting sequences of asynchronous and synchronous counters are the same. How can you
distinguish between the two given time diagrams of both.
