Question

b. A simple two-bit binary counter circuit is shown in Figure Q1(b). The Q0 output of the first flip-flop is the least significant bit (LSB), the second flip-flop's Q1 output is the most significant bit (MSB). Initial two Flip flop outputs are 00. 1. (i) Based on Q1(b), determine the type of counter with reason support (5 Marks) 2. (ii) Draw a time diagram of this counter, including Clock, Q0(LSB) and Q1(MSB). (5 Marks) 3. (iii) Analysis of this counter circuit determine whether it counts in an up sequence (00, 01, 10, 11) or a down sequence (00, 11,10,01). (5 Marks) 4. (iv) Determine what would have to be altered to make it count in the other direction (4 Marks) Figure Q1(b)
