Unformatted text preview: 2.9 The difference between Asynchronous and Synchronous inputs on a flip-flop is that Asynchronous inputs (typically Set and Clear) operate immediately, whereas Synchronous inputs (such as D, or J and K on a JK flip-flop) have their action synchronized to the clock. If there is no clock event, there is no action. The clock input itself is also considered a synchronous input. 2.11 (a) For the setup time, Ts = 10 nS (b) For the hold time, Th = 5 nS...
