Question :
Suppose you are constructing a 3-bit counter using three D flip-flops and some selection of gates. The inputs to the system are Reset (sets every output to zero) and Inc (a signal to increment the counter).
The outputs are the value of the counter C2C1C0. When the counter has the value 7 and is incremented, it should become zero.
Draw the D flip-flop and logic gates for CO (the least significant bit) only. You may use a block diagram for the D flip-flop.
