| Questão | Responda |
| list 3 facts about Asynchronous Counters | 1) Only the first flip-flop is clocked by an external clock the rest are from the outputs. 2) They are slower than synchronous counters because of the delay in transmission. 3) They're also called ripple counters |
| Draw an Asynchronous Counter including the output table | |
| list 3 facts about Synchronous Counters | 1) All flip flops are clocked by an external clock 2) They are faster than asynchronous counters because of the clocking 3) They are an example of state machines design. |
| Draw a synchronous counter including the output table. | |
| What is the change function in counter design | The change function is using the Ps and Ns states. If they are the same it = 0 If they are different it = 1 |
| Under what circumstance does a race condition occur in an Asynchronous logic circuit? | It occurs when two or more state variables are supposed to change simultaneously due to a change in the input. |
| what is the excitation table for a JK flipflop? |
