Briefly describe the operational aspects of bistable, monostable and astable multivibrators. Whichmultivibrator closely resembles a flip-flop?2. What is a flip-flop? Show the logic implementation of an R-S flip-flop having active HIGH R andS inputs. Draw its truth table and mark the invalid entry.3. With the help of the logic diagram, describe the operation of a clocked R-S flip-flop with activeLOW R and S inputs. Draw the truth table of this flip-flop if it were negatively edge triggered.4. What is a clocked J-K flip-flop? What improvement does it have over a clocked R-S flip-flop?5. Differentiate between:(a) synchronous and asynchronous inputs;(b) level-triggered and edge-triggered flip-flops;(c) active LOW and active HIGH inputs.6. Briefly describe the following flip-flop timing parameters:
