(1) What is a flip-flop? Show the logic implementation of an R-S flip-flop having active HIGH R and S inputs. Draw its truth table and mark the invalid entry. (2) What is a clocked J-K flip-flop? What improvement does it have over a clocked R-S flip-flop? (3) Differentiate between: synchronous and asynchronous inputs; level-triggered and edge-triggered flip-flops; active LOW and active HIGH inputs. Briefly describe the following flip-flop timing parameters: set-up time and hold time; pro
